Gass's problem is pretty clearly that the library is absent, yours is
The whole thing works for me in Solaris 2.5.1 too.

This may be a completely silly suggestion, but did you add the new
regex.o to the list of of OBJS in src/main/Makefile? You don't
actually say that you did, and just placing the file in the directory
is not enough.
Another thing: Are you sure that the libgen routine is getting linked
in? Wading through DejaNews gives me some hints that there are stub
routines in libc.a that might get linked in instead. I.e. does the
final gcc command actually contain "-lgen"?
