FYI: Jakub Jelinek from Red Hat has written a patch which changes the
behaviour back to the traditional behaviour:

http://sources.redhat.com/ml/libc-hacker/2005-01/msg00066.html

Thank you, Jakub.

The patch has been applied to glibc CVS, so I suppose it'll eventually
get to gawk too.

But if you cannot wait, you can try to apply the patch to gawk sources, or
to compile gawk using the regex code from glibc CVS.

Have a nice day,
