But you don't have to do that if it is built into the compiler?

Ah, you mean like that. No, that should be necessary if the bindings are always generated on the fly. My answer was assuming how DStep currently is working.

*nods* I think your idea of integrating with the compiler is a sound idea.

Even though a stand-alone tool is just as good in theory I think most developers want as hassle free builds as possible. If one can just point to the OS include directory and import directly that would be very neat.

Currently DStep will just ignore everything in the body of a preprocessor if statement where the condition is false, just like the regular compiler. For example, running DStep on a header file with the following content:

#ifdef _WIN32
char foo();
#else
int foo();
#endif

Will produce on non-Windows platforms:

extern (C):

int foo ();

So DStep works, just that will generate platform specific bindings.

That is good enough if it is integrated with the compiler then.
