I think it was a portability issue.  I have a suggestion for a
replacement library, though.  No dependencies, and very nice
provenance:

http://www.cs.princeton.edu/courses/archive/spr09/cos333/beautiful.html

and something like 30 lines of code.  I think it would serve our
purposes.  If not, I would suggest using Henry Spencer's library.  It's
in the public domain, and small enough to include with the FreeTDS
distribution.  I compiled it for windows quite easily once upon a
time.  

IMO PCRE is overkill for what we need.  

Regular expressions, by the way, can make for hours of facinating
reading. I particularly Russ Cox on the subject,
