For all things T, for all questions of the form:

	T and SunOS conflict.  Is T wrong, or is SunOS wrong?

the probability of the answer being `SunOS is wrong' is about 95%.  :-)

This was fixed some time ago in 4BSD:

	"foo.c", line n: warning: switch expression not type int

Incidentally, switch expressions of type `long' are now legal as well,
so this error message should be changed to `... not integral type'.
