For compatibility with C++ and more reasonable GNU semantics, would we place
make the below program not print 0.  Essentially, the type of all the
enumerators should be the underlying type of the enum, not the type that fits
the init.

#include <stdio.h>
#include <stdint.h>
#include <stdlib.h>
#include <inttypes.h>

int main(void) {
  enum {
    dummy = (1ULL<<63),
    SomeConstant = 0x1
  } MyEnum;

#define MY_MACRO(value) ((value) << 60)

  printf("MY_MACRO(SomeConstant) == 0x%llx.\n", MY_MACRO(SomeConstant));

  return 0;
}
