Re: svn commit: r669927 - in /apr/apr/trunk: build/buildcheck.sh configure.in

-1.  That breaks the build for all maintainers using OS X 10.4.x and
I don't see any reason to require it.

% which autoconf
/usr/bin/autoconf
% autoconf --version
autoconf (GNU Autoconf) 2.59

+1, committed, please review.

'ifdef' would be better:

ifdef([AC_USE_SYSTEM_EXTENSIONS], [AC_USE_SYSTEM_EXTENSIONS], [
AC_AIX
AC_MINIX
])

Isn't it possible to do some m4 conditionals based on the autoconf
version instead?  Not as clean, but it won't force our developers to
upgrade to 2.6x.  I think it'd be something close to:

ifelse(regexp(AC_ACVERSION, 2\.6), -1, [
AC_AIX
AC_MINIX],[
AC_USE_SYSTEM_EXTENSIONS
])

We have 2 choices.

/usr/bin/autoconf --version
autoconf (GNU Autoconf) 2.61

this is the flavor I've used for a very long time to package apr, httpd
for the projects.  It worked fine.

Unfortunately in 2.62 autoconf maintainers reorganized

  dnl Various OS checks that apparently set required flags
-AC_AIX
+AC_USE_SYSTEM_EXTENSIONS
  AC_ISC_POSIX
-AC_MINIX

_AIX and _MINIX are deprecated, and part of AC_USE_SYSTEM_EXTENSIONS
since 2.60.  AC_USE_SYSTEM_EXTENSIONS does not exist in 2.59 and prior.

see both
http://www.gnu.org/software/automake/manual/autoconf/Obsolete-Macros.html
http://www.gnu.org/software/automake/manual/autoconf/Posix-Variants.html#AC%5fUSE%5fSYSTEM%5fEXTENSIONS

Now, these two of a some five potentially interesting toggles were respected
in autoconf 2.62.  Now, without the patch above, ./autoconf emits the error;

$ svn diff -r prev configure.in | patch -p0 -R

I'm unsure if we want to tolerate this warning to maintainers, but unlike
all of the other patches I just committed, this patch does not affect the
run time ./configure user.  So I'll listen to a day or two of feedback and
either let you be convinced, or agree we should back this out.
