The following code does not compile using gcc 2.1 on SunOS 4.1.1.
Is the C code indeed illegal and if so what would the justification be?
I ran into this while trying to compile xmon in the X11R5 distribution.
Using cc (SC1.0 1Mar1991) it compiles without error.

----------------------
int foo(short x);
int bar(short x);

int foo(short x) {} /* this works */

int bar(x) short x; {} /* this does not */
---------------------
gcc bug.c
bug.c: In function `bar':
bug.c:6: argument `x' doesn't match function prototype
bug.c:6: a formal parameter type that promotes to `int'
bug.c:6: can match only `int' in the prototype
