Re: Getting GCC 3.2.3 to compile on cygwin

[Dan Kegel <dank at kegel dot com>]

Thanks, Roland!
That sounds a lot like http://gcc.gnu.org/PR10198
I think the official-ish patch is a bit different from yours;
see http://gcc.gnu.org/ml/gcc/2003-04/msg00538.html
Supposedly that's fixed in gcc-3.3; what error do you get there?

Also, were you able to build binutils for cygwin?  Someone said that was
a roadblock.
