That's interesting. That should be added to https://bugs.gentoo.org/show_bug.cgi?id=491098 especially if that works. Do we finally have the fix for https://bugs.gentoo.org/show_bug.cgi?id=491580 in a snapshot? Last time I tried to build that's where it stopped (binutils-apple).

This is my first OSX experience, so I'm somewhat lost on the standard procedures. I'll post the logs for review. http://dev.gentoo.org/~darkside/tmp/logs/ Starting with Xcode 5, Apple no longer distributes GCC (LLVM backend or otherwise). Instead, both gcc and llvm-gcc are symlinks to clang. What's this got to do with building Apple GCC? Well, Clang defaults to C99 mode (actually GNU-extended C99) when compiling C, but that version of GCC was written in the GNU-extended C89 dialect (-std=gnu89). So, when you try to build GCC, you get these errors: /Users/jolexa/gentoo/var/tmp/portage/sys-devel/gcc-apple-4.2.1_p5666-r1/work/gcc-5666.3/gcc/toplev.c:564:1: error: redefinition of a 'extern inline' function 'floor_log2' is not supported in C99 mode floor_log2 (unsigned HOST_WIDE_INT x) ^ /Users/jolexa/gentoo/var/tmp/portage/sys-devel/gcc-apple-4.2.1_p5666-r1/work/gcc-5666.3/gcc/toplev.h:174:1: note: previous definition is here floor_log2 (unsigned HOST_WIDE_INT x) ^ /Users/jolexa/gentoo/var/tmp/portage/sys-devel/gcc-apple-4.2.1_p5666-r1/work/gcc-5666.3/gcc/toplev.c:599:1: error: redefinition of a 'extern inline' function 'exact_log2' is not supported in C99 mode exact_log2 (unsigned HOST_WIDE_INT x) ^ /Users/jolexa/gentoo/var/tmp/portage/sys-devel/gcc-apple-4.2.1_p5666-r1/work/gcc-5666.3/gcc/toplev.h:180:1: note: previous definition is here exact_log2 (unsigned HOST_WIDE_INT x) ^ HTH.
