Unless you're on a weird machine (e.g., not byte addressible), I 
wouldn't worry about that.  I'd worry more about why 'configure' decided 
that memchr doesn't work on your machine.  What's up with that?  What 
does config.log say?

I suggest running 'configure' without using the '--enable-gcc-warnings' 
option, and/or building without -Werror.  --enable-gcc-warnings and/or 
-Werror work only on reasonably-recent-and-reliable platforms.
