I haven't had time to come up with an example, but given the ability to
extract subexpressions (which the reference regex does) you could do a
simple search and replace on the appropriate subexpressions to convert
them to what you want.

As for adding a regexp library, the regex routines are part of the POSIX
spec. I confess I don't know how that works out on Windows, but if
Cygwin is installed I suspect it would work there too.
