GNU grep only call, or fallback to GNU regex(part of libc) when it
can not compile the regex(for example regexes with backreference \1\2..)
is not supported, in the dfa.

I've seen a lot of bug reports concerning the use of bracket expression
and was unable to reproduce any.  However most where locale dependent
stuff (set LANG=C), range expressions(ex: [A-z]) are locale dependent.
