D - pointers and integers

D doesn't allow to convert integers to pointers. This is great
in general, however, I've came to some problems when messing
with API - things like MAKEINTRESOURCE and MAKEINTATOM require
explicitly defined integer value to be of type char*... not
only these, but there are some constants like IDI_APPLICATION
that also should be char* while having the very exact value;
unfortunately, I don't see any way to do this in D, currently,
other than making them all ints and let user do the proper
casting where necesarry. Walter, do you have any suggestions
how to do this in other way?

Hmm, it won't let you do a cast, a-la:

    cast(void*)3

Sorry, my fault. The code looked like this: const char* a = cast(char*) 666; ... // a few hundred lines later const int b = a; For some reason, compiler says "unable to cast int to char*" (or whatever it was) pointing at the declaration of a rather than b, even though the latter is wrong...
