Hi,
I just wondered if anyone has an opinion on the proposed patches I
send with my last message. Without one of these patches there are
still 94 tests that fail on my Sparc/Solaris 9 system:

I wondered whether I should write down a paragraph that document this
behaviour. But I guess this is unnecessary. As far as I can tell POSIX
reserves the use of alternation ("|") to extended regular expressions.
See, for example:
