As several people have noted, this is indeed not portable.  I agree that the
best way to write this is:

	if (p == '\200')

or whatever the ANSI syntax is for hex constants in strings/characters.  I
will note that one other way to write this, with the new ANSI standard,
would be:

	if (p == 0x80u)

This will coerce p to unsigned.
