I just noticed that this could be simplified:
#ifdef _MSC_VER
struct timezone;
/* Last parameter not used */
extern int gettimeofday(struct timeval *tp, struct timezone *tzp);
#endif
because what POSIX actually says is
int gettimeofday(struct timeval *restrict tp, void *restrict tzp);
and
If tzp is not a null pointer, the behavior is unspecified.
Indeed, we never call it with anything but a null tzp value,
nor does our Windows fallback implementation do anything with tzp.
So ISTM we should drop the bogus "struct timezone;" and declare
this parameter as "void *tzp".
