it seems that the right fix would be to change the declaration
        # define RE_TRANSLATE_TYPE char *
to
        # define RE_TRANSLATE_TYPE unsigned char *
in regex.h .

Could you please verify it?

The regex code is taken from GNU libc.  So you could also try to
copy the posix/reg* sources from glibc CVS on sources.redhat.com .
(The CVS has web access, or I could mail you the sources.)

But it's probable that the CVS version will also require the above change.

Thank you for your help with improving gawk,
