If I compile such code example:
void short_test (void)
{
short x = 0;
func(x);
}
I got following warning messages:
$ gcc -c test.c -Wall
test.c: In function ‘short_test’:
test.c:7:4: warning: implicit declaration of function ‘func’
[-Wimplicit-function-declaration]
So I turn the warning off by using
'-Wno-implicit-function-declaration' and it works.
I think '-Wno-implicit-function-declaration' is the option your are
looking for~ :)
