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.
