For ILP32 (32bit x86) and LLP64IL32 (64bit Windows/mingw) targets, it will use
c_long_long which is outputted wrong. Anyways I fixed the bug with respect of
c_long_long being outputted incorrectly as long_long rather than "long long"
too. (r13-6940-ga7df3bea9cf1e4 and backported to GCC 12:
r12-9370-g429b75db39aa89 ).
