Thanks Russell.
What happens if you compile it all the way, i.e. with a compileable example:
#include <iostream>
#define A() 1
#define B(m) m 2
#define STR(x) STR_D(x)
#define STR_D(x) #x
int main() {
std::cout << STR(B(A)) << &std::endl;
return 0;
}
When this program is executed, it should output "A 2", not "A2".
The reason that I ask is that the only thing I have is the free command line
tools. The included preprocessor, cpp32.exe, produces the correct output. The
compiler proper, bcc32.exe, does not. In other words, the behavior is/was
different with the separate preprocessor vs. the "integrated" preprocessor.
