* shortcut.c (PATH_ALL_EXEC): Add parentheses to avoid a compiler warning.

* exceptions.cc (setup_handler): Clarify debugging message.
* sigproc.cc (proc_subproc): Remove PROC_CHILDSTOPPED test.  It is handled by
normal PROC_CLEARWAIT case.
(wait_sig): Eliminate "dispatched" tracking.  Remove __SIGCHILDSTOPPED test.
Decrement counter again before jumping out of InterlockedDecrement loop so that
subsequent InterlockedIncrement will keep the counter at the correctly
decremented value and also detect when there are pending signals.
* sigproc.h: Remove __SIGCHILDSTOPPED element.
(procstuff): Remove PROC_CHILDSTOPPED element.
