In order to use -pg with g77 in cygwin, you must supply your own -pg built
copy of at least main() from libf2c, but preferably the entire libg2c.
Switching in -pg library support for g77 isn't automatic in cygwin, as it is
in glibc. Even so, availability of -pg is a tremendous advantage in the
Windows world.
