There's already a fix for this in Gnulib: its regex.h
arranges to include limits.h before it undefs and redefines
RE_DUP_MAX.

That reminds me, have you had a chance to look at my patch to
sync Gawk's regex code from Gnulib?  That would fix this
problem for Gawk.  It'd also fix a recently discovered
buffer overrun in the Gawk regex code; see
<http://www.sourceware.org/ml/libc-alpha/2013-01/msg00967.html>.
I'll attach an updated version of that patch.  After applying
the patch, run the command "./merge-gnulib".
