Character constants

Doug Gwyn indicated that one version of a C compiler delivered by one
vendor decided that

	sizeof "this is a big fat string"

was the same as

	sizeof (char *)

which is simply not correct.  Your simple test program may give the
wrong answer if your compiler is buggy.

It may be easier to execute a simple test program, but it may not be
easier to believe the results of that program....
