I would second Suhaib's recommendation to build and install gcc-2.95.2. I
have done this in my B21 snapshot installations. I first installed
make-3.77. There is a minor patch required to make libf2c/libU77/[de]time_.c
consistent with the new <windows.h>, and it's worth while to make sure that
.p2align is configured, even though it's not fully effective because cygwin
does not maintain the required 128-bit stack alignment. I think this
requires installation of a binutils snapshot. I am getting significantly
better performance on my applications than I was getting with LF95, although
this varies according to circumstances.
