It solves all of them, thanks.

"-lregex" is needed by regex-posix.c (naturally ;-), since the default
Windows libraries do not include regcomp, regexec, etc.  There's a
test in configure that first check the standard library link, then
"-lregex" and "-lrx".

However, @GUILE_LIBS@ already gets edited to include -lregex, so
there's no problems here.

"-lole32" (and a few others) come from libregex.la.  However, the
standard link command for the program I'm building (GNU Make, btw)
already includes these libraries even without Guile, so using your
modified guile-2.0.pc.in, I was able to link the program successfully
with no unresolved externals.

Btw, shouldn't guile-2.0-uninstalled.pc.in get the same changes?

Thanks!
