Thanks, I'll try that.

But is there any hope that i386-cygwin32 would be upgraded to 2.95.2?

I figured that i386-netbsdpe can't produce code that runs on an actual
Windows machine, or am I wrong. I need to produce executables to run
on Windows.

Of course, I could go and just boot Windows and use the real cygwin,
but I'd rather not, and on VMWare compiling anything is slow as hell.
