  This bit is cygwin specific, and happens because you're using an old
toolset.  Modern versions of cygwin binutils have that feature enabled
automatically; you'll need to add it to the LDFLAGS manually to avoid the
warning message.

  This is a separate problem, and not cygwin-related; it's very likely to be
more fallout from the recent CGEN re-organisation.  Doug, you out there?
