Not that is of great importance, but does anyone know why int main( void ) { return printf( "%d\n", ( int )sizeof( main ) ); } prints 1 ? :)
It is invalid to use sizeof() with a function type expression (C99 §6.5.3.4 para. 1) and hence this code invokes undefined behavior. gcc gives a warning if you compile with -pedantic, but otherwise it apparently just returns 1;
See the description of -Wpointer-arith in the Fine Manual. Segher
