Bug 308515 – gcc-apple doesn't prepare with >=sys-devel/autoconf-2.64

• Product: Gentoo/Alt
• Status: RESOLVED FIXED

[Description Fabian Groffen 2010-03-08 20:37:11 UTC]

the prepare phase for gcc-apple-4.2.1_p5647 fails with an autoconf error:

configure.ac:113: error: m4_copy: won't overwrite defined macro: _AC_ARG_VAR_PRECIOUS
configure.ac:113: the top level
autom4te-2.65: /Volumes/Scratch/Gentoo/usr/bin/m4 failed with exit status: 1

autoconf version 2.63 works fine.

something here hints to use _force variants:

Confirmed - gcc-apple will prepare with autoconf-2.63-r01.1, but not with autoconf-2.64 or autoconf-2.65.

Created attachment 222835 [details, diff]
Missing m4_undefine

This is how it was fixed in libffi (also in 3.0.9 release). If this is wrong, please let me know... that would mean it's wrong also in libffi's release 
now. :-(

that comment by Ralf Wildenhaus would suggest that the suggested patch would be indeed the correct approach

Thanks, I applied the patch to all 4.2.1-based gcc-apple's.
