That's what I would do.  I find that such problems are largely avoided,
and (in my opinion) the code is clearer, if one treats char as a distinct
type and intermixes it with ints only in certain situations (e.g. using
an int to hold a char value or EOF).  Following that rule, when one wants
to compare a char to a constant, one uses a char constant, not an int
constant.  (Yes, I look for a string terminator as '\0', not 0.)

For those barbarous folk who prefer hexadecimal to octal (God clearly meant
man to use octal, the thumbs are parity bits), X3J11 has added hex string
escapes.
