Switch from guile (1.8) to guile20.
Clean up some pkglint.
New in 5.18.10 - May 2016
* NUL terminate CGI definitions text
New in 5.18.9 April 2016
* When parsing CGI, do not allow spaces to be lost
* In producing usage text, check more rigorously that
option "values" are really not flag characters.
New in 5.18.8 March 2016
* Ensure testing vars start as unset for testing
* happy new year & de-uglifications
New in 5.18.7 December 2015
* Guile 1.6 support was removed
* bootstrapping was made idempotent
* add --enable-static-autogen config option
* add (max-file-time) scheme function (max source file time)
* Allow MAN_PAGE_DATE to override using the date program in
man page templates
* Enable byte-for-byte build reproducibility
New in 5.9.5 - May 2008
* integer number arguments may now have their values suffixed with
one of the letters k/K/m/M/g/G/t/T to signify scaling by powers
of 1000 (lower case) or 1024 (upper case). Specify, "scaled".
* AutoOpts "arg-type" may now be set to "file". Existence of the directory
portion of the name will be checked. The existence (or not) of the actual
file may also be checked. Finally, the file may be pre-opened with either
"fopen(3C)" or "open(2)".
* The "columns" program now accepts a "--fill" option to cause it to fill
text instead of filling columns.
* The tests should no longer indirectly reference installed versions of
the binaries. They should all work out of the build directories.
many bugfixes and feature additions, too much to list here
Thanks to Ulrich Etile for help and testing. (There might be remaining
issues on some platforms, but I wanted to checkpoint before the Q4 freeze.)
There also seem to be issues with guile's thread support.
Changes since 5.6.4 includes:
* Fixed a small timing hole where the read from the read end of the output
pipe of the server shell can fail. (The read is retried.)
* Added a macro for testing mmap failure to accommodate a picky compiler.
* The minor version number is being bumped. There is a new (albeit tiny)
feature being added to the syntax. See the doc on the pseudo-macro.
* Fixed a bug wherein out-of-order definitions could get mistyped causing
various catastrophic results.
* Definition and license text files were mmap-ed in without checking for
the size being a multiple of a page. strlen() would seg fault.
Horrible, horrible design of mmap!
* disable autoopts/test/getopt.test unless autoopts has been fully installed.
(It requires getopt.tpl which requires a fully installed environment.)
* several other usability improvements to the tear off library.
* template shell code may now use a shell function "die" that will print
an error message and shoot down the master autogen process.
* the tear-off/add-in libopts library will now specify that the
"options.h" header is to be installed.
* realpath(3C) usage in libopts has been cleaned up. It is now only used
if PATH_MAX is defined for the platform. canonicalize_file_name(3C) is
used where available.
