Take a look at the bottom of this page:
http://www.astro.uio.no/~steinhh/idl/additions.html
They're designed to work with standard unix regcomp/regexec
functions, but see e.g. http://sunland.gsfc.nasa.gov/info/regex/Top.html
for how to use the GNU regular expression library with the same
interface.
Of course, regexp_replace can be implemented by replacing
subexpressions and then putting the string together again...
