gcc-20010312 build fails on cygwin 1.1.8

Hello,

	I'm trying to build gcc-20010312 on a w2k machine running
cygwin 1.1.8. The compile fails with the following:

./xgcc -B./ -B/usr/local/i686-pc-cygwin/bin/ 
       -isystem /usr/local/i686-pc-cygwin/include -O2

I thought that maybe is was because tconfig.h does not have protection
against multiple inclusion. I fixed that, but I get a hole slew of
other errors. Is there anything special I need to do to get it to
compile under cygbin?

Thanks,
