      cc: add two new #pragma varargck · fe2ccb53
      Russ Cox authored 
      #pragma varargck countpos f 1
says that the first argument to f is
the count of variadic arguments that follow.

#pragma varargck type f t
says that t is one of the allowed types for
a variadic argument to f.
(can be repeated)

combined, these can be used to check the
runtime.stdcall functions in the windows port
or in any other port that needs a vararg list of
uintptrs even on a 64-bit platform (where it is
very easy to pass a less-than-uintptr in the ...).

demo:

typedef unsigned int uintptr;

#pragma varargck countpos f 1
#pragma varargck type f uintptr
#pragma varargck type f void*

int f(int count, ...);

void *v;
char *p;

void
main(void)
{
        f(1, v);  // ok
        f(1, main);  // ok
        f(1, p);  // ok
        f(2, v, v);  // ok

        f(2, v);  // found 1 argument after count 2
        f(1, 'a');  // invalid type INT in call to f
        f(1, 0);  // invalid type INT in call to f
}
