Can anyone tell me why the ANSI C committee changed CLK_TCK to
CLOCKS_PER_SEC, and how this is supposed to be different than the CLK_TCK
that 1003.1 assumes the C standard defines?

They both seem to mean the number of `clock_t' increments ("clock ticks") in
one second, but ANSI has for some reason separated the two uses (for `clock'
and for POSIX `times').
