dfa.c order of include problem

[Aharon Robbins]

Hello All.

On systems where limits.h defines RE_DUP_MAX to be very small (such as
OpenVMS, which defines it to be -1) compiling a regexp can fail.

Although <regex.h> undefs and redefines RE_DUP_MAX, it's included too
early in the process. I am pushing the following change to gawk's copy
of dfa.c. I submit it for your review, as well.

Thanks,

Arnold
