A new set of functions has been added in IC6.1 with the prefix "pcre".
This is 
using the "PCRE" package (Perl Compatible Regular Expressions) which will
make 
us all a lot happier.

The rex functions in SKILL are very old, from the days when regular
expressions 
were simple, and had not been extended in lots of wild and interesting
ways.
The rex functions were left as is for compatibility with existing code.
