The signal handling with window messages is incompatible with non-reentrant
16-bit user.exe module in Windows95... Windows 95 crashes when signal
handler modifies the context of main thread while in user.exe code. The
state of user.exe is unpredictable in this case.
I've just modified the cygwin code - do not send SIGCHLD to parent on child
exit. It's the default behavior on windows 95 (it's still possible to
override it with CYGWIN_SIGCHLD=1 environment variable). On NT the SIGCHLD
signal is always sent to parent. My W95 machine runs now configure of cdk
in one console, and the make of cdk in another console. I'll post the patch
when the both processes will finish successfully:-)
