But I highly recommend not to replace (overwrite) gcc which
ships with Cygwin 1.0 CD. If you download pgcc-2.95.2 for Cygwin v
1.0 CD from my URL
( http://siddiqi.webjump.com ) please install it in /cygwin/usr/local
so you can use g77 and java compiler.
BTW. the libf2c and other patches from Mumit's are applied.
