I was unable to find any reference to this in the djgpp-workers archives
or the bug tracker.  If this has been discussed before, I apologize.

There's a bug in either the libc docs for rawclock() or the function
itself.  According to the docs:

---snip---
     unsigned long rawclock(void);

Description
-----------

Returns the number of clock tics (18.2 per second) since midnight.
---snip---

However, according to the source, rawclock() actually returns the number
of tics since the first call to itself in the program.  This seems to
exactly duplicate the functionality of clock(), so I assume that the
function itself is in error.  A patch is attached.
