This is fixed upstream: http://git.savannah.gnu.org/cgit/m4.git/commit/?h=branch-1.4&id=1359a849055a66eddffe7753485e0f29fb85ef31 > I would have thought that gcc-4.5 or gcc-4.5.1 were the likely cause, > but since nobodyelse has reported it, perhaps it's a glibc-2.12 issue ? > > NB I'm also using --enable-kernel=2.6.33 for glibc. > > Normally, I would just commit this to patches once I was sure the > build works, but I'm still trying Andy's suggestions for glibc so I'm > some hours away from doing that! The git/patch explains everything. It's a posix issue with Glibc. The patch you posted earlier adds two headers that may not be needed. At the same time I looked at the git logs for the m4-1.4 branch, and I didn't see anything else that would affect us, such as compiler or security fixes. robert
