fd_set causes code generator to generate bogus code

[DemiMarie]

If a function uses fd_set as an argument, the generator generates bogus and syntactically incorrect code. It should fail with a better error message instead.

Can you provide an example of the bogus and incorrect code? That would make it easier for me to verify and reproduce the problem.
