I've started on this by changing the mbrtowc module in gnulib to work around the 
future-POSIX incompatibility of mbrtowc in glibc. See:

http://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=b7bc3c1a4e78add4cbad39ae1a0c4fb0747b483f

I plan to change GNU grep to use this new facility, and to add some grep test 
cases for this issue.
