# Note that the actual size of these types is system-dependent, and
2
# cannot be detected before C compile time.  However, the generated C code
3
# will correctly use the actual size of these types *except* for
4
# determining promotion in binary arithmetic expressions involving
5
# mixed types.  In this case, operands are promoted to the declared
6
# larger type, with a bias towards typedef types.  Thus, with the
7
# declarations below, long + time_t will result in a time_t whereas
8
# long long + time_t will result in a long long which should be
9
# acceptable for either 32-bit or 64-bit signed time_t (though admittedly
10
# the POSIX standard doesn't even specify that time_t must be an integral
11
# type).
