I would appreciate it if you could look into this Chris, since using my
build environment, I can compile the 1.3.12 sources and the Cygwin DLL works
fine. However with the binary in the 1.3.12-1 binary distribution, I am
seeing the failures others have experienced, namely with the
NtQuerySystemInformation call failing. Since I can't reproduce the problem
on my machine, I don't really know where to begin fixing it.
I am using binutils 20011002-1 and gcc version 2.95.3-5 (cygwin special).

Chris
