GCC quietly accepts the following: #define A a #define B a #if #A == #B #endif
In fact if we look at the output for the following code: #define A b #define B c #if #A == #B void g(void); #endif We find that "void g(void);" is always outputted so in fact it does not do what David wanted it to do. Thanks, Andrew Pinski
