easy way of copying regex_t ?

Hi all,

I've been working on moving an extension that allows to move the ispell
dictionaries to shared segment. It's almost complete, the last FIXME is
about copying regex_t structure (stored in AFFIX).

According to regex.h the structure is fairly complex and not exactly easy
to understand, so I'd like to know if anyone here already implemented that
or something that may serve the same purpose. Any ideas?

kind regards
Tomas
