In d18f76d I changed compat/regex to use the engine from gawk, there
have been a few fixes of ours to it since then, some of which may be
applicable for upstream inclusion:

    $ git --no-pager log --oneline --reverse d18f76d.. -- compat/regex
    a997bf4 compat/regex: get the gawk regex engine to compile within git
    de83172 Change regerror() declaration from K&R style to ANSI C (C89)
    b50f370 compat/regex: define out variables only used under RE_ENABLE_I18N
    178b331 compat/regex: get rid of old-style definition
    ce518bb Fix compat/regex ANSIfication on MinGW

But I don't think we should be taking patches like these. I think they
should instead be sent to the upstream gawk developers who I'm sure
would be happy to take them.

But this is not code that we're maintaining, and patches like these
just make it harder to merge the code from upstream.

You're right. I will send this patch to gawk developers.

Thanks to your advice!

If you're doing that anyway it would also be very useful to see if
they'd be willing to take the the rest of the patches we've
accumulated since we initially brought it into our tree. I.e. the ones
I showed in the shortlog I posted.

Hi,
you might want to fix the grammatical errors instead:
"If an error occurs, ERR is set to the error code, and NULL is
returned.", or something like that, I haven't actually read the code.

Best,
