[PATCH] Let RTEMS provide clock()
- From: Sebastian Huber <sebastian dot huber at embedded-brains dot de>

- Subject: [PATCH] Let RTEMS provide clock()
- Authentication-results: sourceware.org; auth=none
Newlib uses _times_r() in clock(). The problem is that the _times_r()
clock frequency is defined by sysconf(_SC_CLK_TCK). The clock frequency
of clock() is the constant CLOCKS_PER_SEC.
FreeBSD uses getrusage() for clock(). Since RTEMS has only one process,
the implementation can be simplified.
