static specifier has no effect when only used in function declaration

[Daniel-Cortez]

Issue description:

Using the static specifier in a new-style function declaration, but omitting it in the definition

// file1.inc
forward static Func();
Func(){}

results in static having no effect on the function, so the latter can be called from other files

// main.pwn
#include "file1.inc"

main()
{
	// This compiles without errors or warnings, even though normally
	// the scope of Func() is expected to be limited to "file1.inc" only,
	// as the function was first declared as "static".
	Func();
}

Minimal complete verifiable example (MCVE):

See above.
