The latest release of g77 is g77-3.4.1, part of gcc-3.4.1.  Binaries can 
be found by following the entry "Binaries" in the left column of our 
home page (http://gcc.gnu.org).

In general it will.  Little has changed over the years in the library.

There probably is, but I do not know of one off-hand.  Look into the 
mailing list archive at http://gcc.gnu.org/ml/gcc-testresults/2004-07/ 
to see who uses a cygwin system and ask them how to get a binary version 
of gcc-3.5.0.  Note that that version hasn't been released yet and is 
*experimental*.

See our "Binaries" entry that I alluded to above.

OK, if you think there's a real compiler bug, contact us again at 
http://gcc.gnu.org/bugzilla/.

Thanks,
