If you are porting code to CYGWIN32 that has already been ported to the
WIN32 API, and which uses the send/recv socket calls etc, beware that it
might well end up calling the wrong functions.  The file winsock.h
defines send as a PASCAL function, while socket.h defines it as an
ordinary C function.  Calling the wrong one is a good recipe for
failure.  The safest thing is probably to -UWIN32 and rebuild all of
your code.  If you get random failures in send/recv, check whether the
real function being called is send or send AT 16.  The latter of these is
the PASCAL imposter.  The assembly code mode of the debugger will show
you this.
