The C library contains the regex functions on pretty much any unix
platform, not just GNU.   This includes Solaris, AIX, IRIX, HP-UX,
*BSD, etc.

One thing that can be done already now without changing TRE (yet) is
to call one of the tre_ functions which already exist.

For example, if you add a call to tre_version() you can be pretty sure
that the reg* functions are also coming from TRE.  Screwing that up
would require somehow managing to link only some of the symbols from
libtre and the rest from libc -- not likely to happen.
