Hmm, why not? Shouldn't they be working? What versions of m4 and
Autoconf
were you using? Let's try to see what the underlying problem is
first,
before removing this from regex.m4.
Well, I have to admit, I'm not an expert at autoconf or m4... The
versions I'm using are
autoconf: 2.59; m4: 1.4 (on Mac OS/X 10.3)
Autoconf: 2.59; m4: 1.4.1 (on RHEL 3).
You should upgrade to m4 1.4.3, unless these older m4 versions have
been patched heavily.
In both cases running sh -vx configure showed that these looked like
they were not doing anything at all. That is, it was as if they were
comments and the enclosed code was just eliminated.
That's the expected behavior. The m4_syscmd code is executed when
'autoconf' is run, not when 'configure' is run. So it sounds like
things were working correctly for you.
OK. I'll work that back in (or up date from CVS if you've patched my
patch...) and see if an upgrade to the newest m4 fixes things.
Thanks,
James
PS. I'm still not able to get the regex.c/h code to compile on os/x
10.3; I'll work on that as time permits as well.
