The problem I've had in the past is that Float in Ada sometimes means
something else in C, say long float.  Make sure the underlying
representations are the same.

If you're using Ada 95, you shouldn't have a problem if you stick to the
types in package Interfaces.C, and remember to use pragma Convention (C)
on your subprograms.
