BTW, expanding on Andrew's comment, ISTM we could move the kernel call
out of the macro, ie make it look like
#define CHECK_FOR_INTERRUPTS() \
do { \
if (UNBLOCKED_SIGNAL_QUEUE()) \
pgwin32_check_queued_signals(); \
if (InterruptPending) \
ProcessInterrupts(); \
} while(0)
where pgwin32_check_queued_signals() is just
if (WaitForSingleObjectEx(pgwin32_signal_event,0,TRUE) == WAIT_OBJECT_0)
pgwin32_dispatch_queued_signals();
This would save a few bytes at each call site while not really costing
anything in performance.
