Hello,

I have tried to rebuild GCC 3.2-3 it builds the execs but unfortunately it
bombs out making some of the libraries.

I may have mised something but I am not sure. How do I build CygWin GCC
3.2-3 ?
I have installed CygWin then changed to the 'i686-pc-cygwin' directory then
done a 'make'.

Have I missed any configuration steps, or is GCC's library broken ?

It looks like the following file is broken :-

    libstdc++-v3/libsupc++/pure.cc
