Summary: Superfluous warnings

Initial Comment:
To limit the size of the final code, I use
macro's and defines whenever possible. However
this can lead to an enormous amounts of warnings.
Eg.,

#define MAX(a,b) ( (a)>(b) ? (a) : (b) )

#define A (1)
#define B (2)

int main( void )
{
   return MAX(A,B);
}

Generates:
warning *** conditional flow changed by 
optimizer 'file.c(10)':so said EVELYN the modified DOG
warning *** unreachable code file.c(10)

It would be nice to have a commandline option to
disable these warnings since I expect the compiler 
to optimize this.
