Not sure if it works to change type from 

  mp_limb_t foo (void); // Now aka mp_limb_t foo()

to

  mp_limb_t foo (...); // A varargs function

or of an initial mandatory argument is required, say

  mp_limb_t foo (int dummy, ...);

I guess the "pure C" way would be to have use a different type for each
needed function signature.

I'm not familiar with these calling conventions tests, is it some
assembly function setting up the call?
