My two cents on the behavior of the 'constant' -32768 in C.  If something is
#define ed as -32768, remember that that means a _textual_ substitution will
be made wherever that thing appears (in contrast to a numeric substitution).
So the normal rules for integer constants apply (rather than some special
rule that might apply to preprocessor actions: the preprocessor action is
simple).  Integer constants don't have leading signs.  -32768 gives the
result of applying unary minus to the integer constant 32768.  And on a 16
bit model compiler, there isn't an integer 32768.  So the value of -32768 is
free to vary depending on context.  One hopes a warning message is generated
(it is in Mark Williams C).  Frankly, -32768 is such a convenient value for
flags on a 2-s complement machine, that I'd like integer constants to have
an optional leading sign, but it isn't defined that way.
