#pragma unused can't be used on functions

[b0mbie]

#pragma unused g_SomeStatic
any g_SomeStatic;

void SomeFunction() {
	any someLocal;
	#pragma unused someLocal
}

// This will report `error 017: undefined symbol "SomeFunction"`.
#pragma unused SomeFunction

... yields:

pragma-unused.sp(10) : error 017: undefined symbol "SomeFunction"
    10 | #pragma unused SomeFunction

This became a problem when trying to compile TF2Attributes. The code compiled on 1.11.0.6970, but didn't on 1.12.0.7177 and 1.13.0.7190 (latest versions for each major release). Considering what #pragma unused is used for, it didn't seem to be intentional behavior.
