Interesting. How widely supported is this? From the look and general 
usefulness, I'd suspect it to be a GNU extension. If both GCC and MSVC 
support this, that would be great.
This (probably) leaves compilers like BCC and Watcom in the dark though 
(but how many people actually use Allegro with those?)
