well, if some of you guys aren't going to believe Doug Gwyn and Chris
Torek, will you belive your own C compiler?

following is a script testing pcc, gcc 1.31, and vcc (DEC's own) on Ultrix 2.2:
(apologies for the quickie C program...)

Script started on Thu Mar  2 20:20:30 1989
granite [51] cat xint.c
main()
{
	printf("size is: %d\n", sizeof('x') );
}
granite [52] cc xint.c
granite [53] a.out
size is: 4
granite [51] gcc -v
gcc version 1.31
granite [52] gcc xint.c
granite [53] a.out
size is: 4
granite [54] vcc xint.c
granite [55] a.out
size is: 4
granite [56] 
script done on Thu Mar  2 20:21:18 1989

hmm... either 'x' is an "int" or a lot of compiler writers are wrong.
(or "sizeof(char)" was suddenly and unexpectedly given a promotion.)
