:Just curious...
:
:If EOF is 'int -1' (0xFFFFFFFF), then having is*( _unsigned_ int) will
:solve the problem:
:Programmer will need to explicitely cast values to unsigned int,
:resulting in 0xFF for char -1 and 0xFFFFFFFF for EOF.

:PS. I never have read the SUS, so don't shoot me dead... Just ignore
:if inappropriate :)

    It wouldn't work anyway, even if we could (and we can't since the
    type is specifically an 'int').  A char x = -1 will still wind up
    being 0xFFFFFFFF when cast to an unsigned int.
