`error: found trailing tokens after preprocessor expression` in legit code.

[MarekKnapek]

Steps to reproduce.

• git clone https://github.com/PhilippRados/wrecc.git
• cd wrecc
• cargo b
• ./target/debug/wrecc test.c

test.c

#define mytest(a, b) 0

int main(void)
{
#if mytest(1, 2)
        return 1;
#else
        return 2;
#endif
}

Actual result:

error: found trailing tokens after preprocessor expression
|  --> in test.c:5:5
|
5 #if mytest(1, 2)
|     ^
1 error generated.

Expected result:

• No error message.

Yes that's probably because of the currently unsupported function-like macros. I will focus on the preprocessor again after this next release.
