multi-character character constant !

u.u_exdata.ux_mag == SCRMAG makes me wonder...

$ cat x.c
#include <stdio.h>
main() { int c = '#!'; printf("%x", c); return 0; }
$ make x
cc     x.c   -o x
x.c:2:18: warning: multi-character character constant
$ ./x
2321
$ man ascii

| 20 sp | 21  ! | 22  " | 23  # | 24  $ | 25  % | 26  & | 27  ' |
...
