Recent(ish) src/libc/ansi/time/ctime.c changes add about 4.5k more
size to the final stripped binary:

#include <time.h>
int main () {
 return time(NULL);
}

Linking against v2.04 from 2011-10-01 gives a 91648 bytes a.exe,
whereas linking against v2.04 from 2014-04-20 gives a 96256 bytes
a.exe. (not mentioning at all the crazy sizes themselves which is
irrelevant to the present case at hand.)  A "return 0" instead of
a "return time(NULL)" yields a 52736 bytes exe, so ctime.c stuff
is adding about 43k size.

time() calls gettimeofday() which calls 0x2c and 0x2a dos functions
and calls ctime.c::mktime() where the additional bloat happens.

Is there no other way of reducing the code size here?
