Memory management, portable types, math constants, and timing.

Author: Pascal Getreuer getre.nosp@m.uer@.nosp@m.gmail.nosp@m..com

This file implements a function Clock, a timer with millisecond precision. In order to obtain timing at high resolution, platform- specific functions are needed:

On Windows systems, the GetSystemTime function is used.
On POSIX systems, the gettimeofday function is used.

Otherwise as a fallback, time.h time is used, and in this case Clock has only second accuracy. This file attempts to detect whether the platform is POSIX or Windows and defines Clock accordingly. A particular implementation can be forced by defining USE_GETSYSTEMTIME, USE_GETTIMEOFDAY, or USE_TIME.
