- Quadrigraphs
This feature was present in autoconf 2.50 but was not documented.
For example, `@<:@' is translated to `[' just before output. This
is useful when writing strings that contain unbalanced quotes, or
other hard-to-quote constructs.
- m4_pattern_forbid, m4_pattern_allow
- Using autoscan to maintain a configure.ac.
- Fixed Fortran name-mangling and link tests on a number of systems,
e.g. NetBSD; see AC_F77_DUMMY_MAIN, below.
- cross-compilation
$build defaults to `config.guess`, $host to $build, and then $target
to $host.
Cross-compilation is a global status of the package, it no longer
depends upon the current language.
Cross compilation is enabled iff the user specified `--host'.
`configure' now fails if it can't run the executables it compiles,
unless cross-compilation is enabled.
- Cache file
The cache file is disabled by default. The new options
`--config-cache', `-C' set the cache to `config.cache'.
... and many others, esp. bugfixes. Check the docs!
To cite announce on freshmeat for Changes:
Various bugfixes and enhancements collected during the past two years
since the last release. Way too many to mention them all here. The
ChangeLog is included in the package.
- New, optional Makefile variable HOMEPAGE, specifies a URL for
the home page of the software if it has one.
- The value of HOMEPAGE is used to add a link from the
README.html files.
- pkglint updated to know about it. The "correct" location for
HOMEPAGE in the Makefile is after MAINTAINER, in that same
section.
If perl is not installed, there will be no autoscan script, so
construct the packing list at installation time, when the contents are
known.
Also remove an erroneous check for a texinfo dir file.
Use uname -s to work out the Operating System.
FreeBSD has install-info and /usr/share/info/dir by default.
NetBSD doesn't, so, for now, don't try to do this on NetBSD.
