Thanks for fixing that.

I had originally thought to put the "#define _LINUX_SOURCE_COMPAT 1" 
into AC_USE_SYSTEM_EXTENSIONS, which would have fixed it in a different 
way. However, it's not really an extension to AIX but more of a change 
(since it changes the strerror_r API) so I didn't do that.

With so many Gnulib modules now defining _LINUX_SOURCE_COMPAT directly 
or indirectly, we're probably not that far from what my original thought 
would have done, in a practical sense. But it's clearer to have a 
separate macro since it really is a behavior change, not an extension.
