Seemed relevant, so I'll push it into the mailing list again.

Well, I'm using gcc, which is pretty consistent between platforms, though 
hardly perfect.  (You think I'd be stupid enough to try circle on C/Set++ or 
something?  Hah!)  Also, UNIX and OS/2 are both 32-bit, so that funny 
variable declared in SIGNAL.H (I think sig_atomic_t or something) should 
still be a 32-bit deal.  Hence, if gcc normally considers a typedef int 
to be 32-bits rather than 16-bits, it should be the same for OS/2.  
Though I can't say I've checked.  I didn't get any warnings about that, 
though, and I know The Muds Whose Names Are Not Mentioned But One Has To 
Do With Soldiers of Fortune gave me a whole slew of warnings when I tried 
to compile it on Linux.  (I gave up pretty quickly when it became 
apparent that it wasn't going to work.)  Anyway, the warnings were along 
the lines of time_t being treated as a short int;  since we all know 
time_t is really a long int, TMWNANMBUHTDWSOF was assuming that a typedef 
of int is interpreted as a long int.  That was obviously incorrect on the 
Pentium Linux machine.  (Can't Pentiums handle 64-bit things?  Or am I 
confusing the CPU with the PCI bus again?  Damn, you know they're so 
similar.)
