I am attempting to build the gcj for Windows in a unix-esque shell Trying again with gcc-4.6.3. I have downloaded a program called mcpp, which is apparently a c preprocessor that works. ./contrib/download_prerequisites; works okay. ./configure; works okay.
AKAIK, configure in the source tree is stringy discouraged and not well tested. Read the "Installing GCC: Configuration" again.
