Subject: calling c code from pascal
Date: 2 Aug 2001, 15:09:01

In pascal (unlike C and many other languages) you don't need (and
apparently shouldn't) use empty brackets after the function name if it
does not have arguments. The keyword allegro_init is explicitly stated to
be a function and parser clearly expects an argument here.
So your declaration should be:
function allegro_init:integer;asmname ...
