Following Gnu installation instructions, I made a directory "w98c" in /usr/local. I first placed the downloaded version of gcc (I've tried 3 now; gcc-3.3, gcc-4.0.2 and gcc 4.1.1) in / directory. I changed "Autoexec.bat" to reflect the PATH to C:%PATH%;C:\CYGWIN\GCC-3.3\GCC. Invoked Cygwin, went to the "w98c" directory and typed in "/gcc-3.3/configure". It complained about not finding a valid c compiler - please set CC variable in my environment. I did just that in the "Autoexec.bat"; "SET CC=TO C:\CYGWIN\GCC-3.3\ Attempted re-configure, same complaint. What am I doing wrong.
