In that case, strictly speaking, you couldn't use the library from C, or 
Ada, or any other programming language. If you're willing to assume that the 
code conforms to the normal conventions for the target (that is, works like 
the "standard" C compiler), then of course Ada (via Interfaces.C) will work 
the same way.

But clearly, if this is compiled by a "weird" C compiler, you couldn't use 
it from gcc or MS-C anymore than you could use it from Ada. You could only 
use it from the "weird" C compiler, and your problem statement says that you 
don't know what that is. In other words, it is unusable, and you'd be best 
off rewriting it in Ada (or even a known C).

Nothing Ada-specific about that.
