Regex
-----
This is a port of the regex library sources as found on the O'Reilly
4.4BSD-Lite CD.
This is ONLY of any use if you are using UnixLib to port sources. If you
are using Acorn's libraries then this is not going to work...
Installing
----------
Copy o.regex to !UnixLib.clib.o and h.regex into !UnixLib.clib.h.
Using
-----
Add in Unix:o.regex as a library in the Makefile _before_ Unix:o.unixlib,
otherwise you will get gripes about undefined symbols from the linker.
Anything that then includes <regex.h> should then compile happily.
Problems
--------
None that I've encountered so far, mostly the source required butchering
to get rid of includes that UnixLib hasn't got, and the prototyping form
found in 4.4 sources along the lines of __P((..)) which makes the compiler
have a fit.
any other gripes, or comments, I'm contactable at:

[End-note: if you are wondering why I ported this little bundle of joy,
it was in order to support the regular expression routines present as an
option in GNU Scheme---they seem to work so I have some confidence that this
lot is correct.]
