I don't know about AIX, but in Linux for instance, that's not possible,
easy to understand really, when you consider that the size of some data
types changes, but the libraries calling each other don't know that.

Remember that shared libraries usually do not contain any information
about function call parameters, just the start addresses of the
functions. So when one library pushes a 32 bit number onto the
stack and another tries to read a 64 bit number, there will be trouble.
