Chris Ender said he wanted to call Alsys x86 from C....
Assuming your compiler is similar to other Alsys compilers,
check your documentation for pragma Call_In.

I'm trying to call an Ada procedure from a C program, and was wondering
how this was done before the Export pragma was there? I can't get the
linker to find the Ada routine. I'm currently using Alsys on x86 UNIX.
Any suggestions would be appreciated.

The answer is "with great difficulty!"
You are unlikely to succeed flailing around. You need to talk to your vendor,
and see if they provide some kludge for achieving this goal (perhaps using
the 'Address attribute on the subprogram), but it is not something that
there is any standard way of doing in Ada 83.
