This change was rejected by Uli on ABI compatibility grounds.

I don't think support for >2GB subjects is worth dropping support for 
collation symbols, so gnulib should IMO remove this check, and (I 
disagree with Jim) LFS in the meanwhile should use 
--without-included-regex despite the failure.  It looks sufficiently 
obscure, sed may care but grep most likely doesn't.

We should look into the failure and fix it, either in grep or glibc.
