IMHO, the win32-specific function list is already too long. Don't get me 
wrong, I like for Allegro to allow as much as is possible and disallow as 
little as possible, but we should motivate people to write platform 
independent code. Having a lot of platform specific functions conflicts 
with this goal, IMHO.

Couldn't you just handle the F1 key instead?

Isn't there some way to interface with the message loop already?

If something like this is going to be added, I'd rather see that it was 
added as a public function of the type

allegro_set_signal_handler(int al_sig, void (func)(void))

with Allegro #defining a number of signals (or messages in Windowsspeak) in 
a platform independent way. A possible list could look something like

#define AL_SIGHELP		somenumber
#define AL_SIGTERM		someothernumber
#define AL_SIGSEGV 		yetagainsomeothernumber
etc.

This may be overdoing it for a game programming library, though.
