Upstream news:
* Noteworthy changes in release 2.6.4 (2017-05-06) [stable]
** build
*** The indent target now knows about flex's new (as of 2.6.0)
layout. The indent rules it would apply are not correct and do
need to be fixed.
*** The files included in the flex distribution are now built by the
version of flex that is included in the distribution.
*** The configure script has a better idea of which headers are
required to build flex. It will also error when missing functions
are detected.
*** We have lowered the versions of automake and gettext that
configure.ac lists as required for building flex. In autogen.sh,
we now check for how to call libtoolize and use what we find in
the rest of the script.
*** Since files in lib/ are picked up as needed by src/, we no longer
generate a Makefile for that directory.
*** Flex can be cross compiled.
** documentation
*** Some typos were removed from the manual.
** scanner
*** Some minor performance enhancements.
*** We honor user defined yy_* macros again. We are also more careful
to not leak macro definitions into header files.
*** A number of portability fixes were introduced so building flex is
more reliable on more platforms. Additionally, outdated function
calls were removed.
*** When building the flex executable itself, %# comments from
flex.skl are removed when generating the C source code array. This
reduces the size of flex.
** test suite
*** All scripts in the test suite are now run by $(SHELL) and the
needed portability fixes have been included.
*** Test suite dependencies are handled much better. This only matters
if you are actively developing flex or its test suite.
*** Tests that depend on platform dependent features now properly skip
when those platforms are not present.
*** When running "make check", you can now pas V=0 to silence more of
the build. This is useful when you're less connncerned about the
details of building and linking the test programs themselves.
* version 2.6.3 released 2016-12-30
** scanner
*** several bug fixes resolved problems introduced in recent flex
versions regarding processing of comments, literals and various
quoting scenarios.
*** If the path to m4 was sufficiently long, a buffer overflow could
occur. This has been resolved. The fix also removes dependence on
the constant PATH_MAX.
** build
*** A new configure option --disable-bootstrap changes the behavior of
the build system when building flex. The default
"--enable-bootstrap" behavior is to build flex, then to use that
flex to build flex again. With --disable-bootstrap, the scanner is
simply built by sedding the scanner source. This is friendlier to
cross compilation.
*** The compatibility functions in lib/ are no longer built as a
library. Instead, they are built as $(LIBOBJ) objects. This is
simpler and friendlier to cross compilation.
*** It is now possible to build flex without building the accompanying
libfl. This is friendlier to cross compilation. See the
--disable-libfl option to configure. Resolves#99.
*** the PIC version of libfl was not correctly built. It is no longer
included in the build/installation targets of flex since it was
unused.
*** the distributed man page is only rebuilt when the relevant source
files change or when the binary doesn't exist. In particular, this
is friendlier to cross compilation. Resolves#108
** test
*** the shell scripts in the test suite are more portable across different shell implementations.

"v2.6.2 introduces behavior change that is incompatible with previous versions"
This fixes at least doxygen
Slightly based on wip/flex by Makoto Fujiwara and Juraj Lutter.
* version 2.6.2 released 2016-10-24
** flex internals
*** a segfalt involving yyrestart(NULL) has been fixed
*** flex should now handle quoting when mixed with m4 processing correctly
*** flex handles `[[' and `]]' correctly
*** flex no longer generates non-ANSI code
*** more compilation warnings were squashed in generated scanners
*** prevented a buffer overflow that could occur when input buffers were the exact wrong size
** test suite
*** input filenames on MSWindows are now calculated correctly
*** general code cleanups in a number of tests now make the test suite compile much more cleanly
** build system
*** the xz archive has been replaced with an lzip archive
*** a new option to configure --enable-warnings to encapsulate passing
of warning-related flags which is useful in testing flex
*** make indent now works for out of source builds
*** Portability warnings when generating Makefile.in files are now suppressed; they were just noise and the use of GNU extensions in Makefile.{am,in,} was intentional and well known.
** bugs
*** resolved gh#67
** new sv translation from the translation project
* version 2.6.1 released 2016-03-01
** flex resources
*** The flex project is now hosted at github. Consider this a "period of transition". In particular, you should start at https://github.com/westes/flex for the flex codebase, issue tracking and pull requests.
*** New releases of flex are to be found at https://github.com/westes/flex/releases.
** flex internals
*** Flex now uses more modern and more standard names for variable types. There's more work to be done on that front yet, though.
*** A number of compiler warnings have been remedied.
*** Line directives should now work as expected and be absent when that is expected.
** test suite
*** When running the test suite, c++ files are compiled with the c++ header inside the flex distribution, rather than relying on the build system's flex header , which might not be installed yet or which might be out of date with respect to what flex tests expect.
*** Some portability fixes in the test suite such as opening files for reading in binary mode
** Building flex
*** The file src/scan.c asdistributed with flex source is now built with the current version of flex. Occasionally this had to be done manually to pick up new flex features. It's now just a part of flex's build system.
*** The pdf version of the manual is no longer distributed with flex, although if you have the texinfo package installed, you can still build it.
*** lots of general build system cleanup
*** the build system tries a bit harder to find libtoolize and texi2dvi.
*** When help2man and texi2dvi are missing, the error messages are now much more helpful.
** bug fixes
*** resolved github issues #53, #54, #55, #61.
*** Resolved sf bugs #128, #129, #155, #160, #184, #187, #195.
----------------------------
Recent commit update to 2.6.1 has problem, reverting now, thanks joerg and wiz
- Bison is required to build without pre-generated files, but
Bison needs flex, thus cyclic-dependency problem
- Missing to include gettext-tool/buildlink3.mk

Changes:
* version 2.6.0 released 2015-11-17
** User Visible Changes
*** C++ scanners now use references instead of pointers. See the manual for details.
*** A number of compiler warnings were addressed, so flex generated scanners should be quieter under compiler warning scenarios.
*** Allow error reporting routines to accept varying number of arguments
*** Removed deprecated 'register' storage class specifier
*** Changeed output formats from octal to hexadecimal
*** check limits before using array index cclp; resolves sf-166
*** Suppress clang warning about empty @param paragraph; resolves sf#158
*** Fixed malloc/realloc replacement, resolves sf bug#151.
*** Adjusted buffer sizes on ia64.
*** various documentation and code clean up fixes: resolves sf bugs #167, #168, among other patches.
** Flex Internals
*** flex is now organized into subdirectories. This keeps the tree neater at the top level and puts like things near each other and unlike things away from each other.
*** The test suite has been reorganized and is now run with the parallel test suite harness from automake.
*** Cleaned up the automake parts of the build system to better reflect what automake does on its own. Also added a call to libtoolize in autogen.sh because autoreconf gets confused without a prior run of libtoolize.
*** po/Makefile now includes a rule to fetch the latest translations from the translation project. "make -f po/Makefile getpo" from the top level of the flex tree will fetch the files.
*** New da translation from the translation project

Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden). All existing
SHA1 digests retained for now as an audit trail.
Now, unwanted configure script timestamp update issue is resolved, and unwanted
documentation regeneration will not be happened anymore.
TeX related tools are not required in any case.
Additionally, PDF document is already in distibution, so no reason to prevent
installation.
Bump PKGREVISION.

"This is a Hail Mary situation. It seems to work."
It doesn't reliably on NetBSD-5 or -current; namely, it makes flex
spit out a "Broken pipe" when presented with an input file on stdin.
Finding the problem area and suggesting a workaround kudos mlelstv.
There are better ways to fix it properly, which will be employed
in Due Time.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
