I am now trying to use #define USE(x) x = x; rather than the #pragma or the __unused__ attribute.
If I put this in the source file, it works. I tried putting this in the prefix.pch file, and it doesn't have an effect. Can I put a #define in the prefix.pch file?

Our code has the following macro, designed to defeat even the smartest optimizing compiler:
#define USE(x) {Int _y_ = ((Int)(long)&_y_, x, 1);}
It also has simpler versions of the macro for compilers that don't need the complexity.
