Then we should add a separate header for this purpose.

One thing is serving more than one master and having the occasional 
#ifndef GREP, another thing is doing things twice in grep (via gnulib 
and explicitly in dfa.c).

setlocale, static_assert etc. should be in a dfacompat.h file that is 
not shared between grep and gawk and could also include the #define for 
GREP and GAWK symbols.
