But it works well. Windows NT + layer of cygwin Posix emulation dll
(1.3.5) and gcc 2.95.3-5 (cygwin special) running on the top, for GDB
and GDBServer 5.0 compilation. The 2 win32 runtime run correctly.

I've heard that some difficulties exist to catch signals thru cygwin
layer and that the classical signal(), raise() ... primitives don't
"work" well but I don't have any info about it.
