current gnulib regex breaks in gawk

[arnold]

Hi.

I happened to notice that regex has been updated with new, er, stuff.

Dropping the code into gawk, including copying over attribute.h,
dynarray.h and malloc/*, doesn't work. Compilation chokes.

I have not yet investigated what the changes are, but I have to wonder
if the churn is really needed?

Running gnulibtool on gawk isn't the direction I want to go, either...

Thanks,

Arnold
