The above macros are defined usually in math.h.
macro NULL is also defined in <cstddef>
Worth mention: NDEBUG:
The effect of  including either <cassert> or <assert.h> depends each 
time on the lexically current definition of NDEBUG.
This means, NEVER include cassert or assert.h in pre-compiled headers.
In Mac OS, this may be similar with macro DEBUG in Debugging.h. If so, 
we NEVER should include Debugging.h in pre-compiled headers, too. (as i 
know, metrowerks includes Debugging.h in its precompiled headers.)

Correct. Most of MSL macros begin with _MSL_*. (CW 8)
The old macros must be fixed.
