Using #define's in .m files is allowed, right? Such as:

In .pch file:

#include "bob.h"

In bob.h:

#define bob(x) {if(!(x)) SysBeep(0); }

In .m file:

void blah(void)

{

bob(SomethingThatReturnsFalse());

}

The .pch file is being preprocessed for both c++ and objc. The problem arises when I try to build my release config, in which case the #define is empty:

#define bob(x)

Everything compiles, but the linker says _bob is undefined. When I preprocess a .cpp file that uses bob, I see the expanded macro in the .i file. But when I preprocess a .m file, I see the UNexpanded macro name, like the preprocessor is not really doing anything with #define's.
