GLOBAL cannot recognize following macros and functions.
1. Macro which doesn't end with ';'.
GLOBAL cannot recognize func() after M(a), because M(a) seems to be
function definition.
#define M(a) static char *string = a;
M(a)
func() {
...
}
It should be follows.
#define M(a) static char *string = a
M(a);
func() {
...
}
2. Macro which is a renamed function.
#define func _func
_func() {
...
}
main() {
func();
}
In fact, main() calls _func() instead of func() but GLOBAL cannot
recognize it.
