It may be UB, but several popular compilers support it anyway. I've done #define int ERROR to force myself to use the equivalent of int32_t instead of built-in types. By the time I got around to int main(), I had forgotten about the macro and wondered why the heck my code wouldn't compile.

| Oct 1, 2012 at 13:44 | comment | added | Dan | You'd have to make it the first line of your main, after main is defined... | |

should work as well and is the same length error: '::main' must return 'int' (minGW 4.4) but #define float int works fine

| Sep 28, 2012 at 20:07 | comment | added | Dan | Fred, can you cite your sources? The GCC cpp docs say "You may define any valid identifier as a macro, even if it is a C keyword." | |

#define int float is actually undefined behavior. You are not allowed to give keywords new meaning.
