When trying to build GNU Emacs 25.0.50 from bzr trunk, revno: 118066 from Mon
2014-10-06 20:19:10 -0700 (UTC+2), on PPC (PowerPC 7447A) Mac OS X 10.4.11,
Tiger, both Clang 2.9 and 3.0, as installed by Macports, fail to compile the
source file lib/strftime.c:

In the next days I'll try to build Clang 3.1, 3.2, etc. Build succeeded with
GCC 4.2.
