I have no idea.  regcmp/regex are very old functions for regular
expression handling, back from the System III days.  These functions
have been superseded at least three times.  The current implementation
is the POSIX functionality as described on

  http://www.opengroup.org/onlinepubs/009695399/functions/regcomp.html

This is also implemented in Cygwin.  If you need portable regexp
handling, consider to port your application to the POSIX variant.
