	Good answer!  however, be aware that the libPW.a archive has all
sorts of things in it that could potentially conflict whit software from
all over the place.  For example, there is a "rename" entry in the PW
library that is NOT posix or BSD compatible!  Trying to use libPW in
a situation where you need a posix rename(2) is going to cause trouble.

	The best solution I have found was to use that ar command to
extract the two object modules concerned, regex.o and regcmp.o, from the
libPW archive and make another archive /usr/lib/libregex.a to hold them.
Then for programs that need regex, I can tell the makefile to include
-lregex in the link step (as a termial argument to the c compiler).

	BTW, if you want posix stuff for some of the older system 5s out
there (like sVr2) check out the posix library that Eric Raymond has in
the beta TMNN-netnews (available from uunet).
