In 32-bit builds, int and long are both 32-bit integers; they're only different in 64-bit builds. It'll only cause problems if you're doing something that requires strict type checking, but otherwise, it should just work.

constructor cannot be overloaded?
I have a C++ class I use to wrap CGRect:
class
Rect : public CGRect
{
public:
Rect();
Rect(const Rect inRect);
Rect(const CGRect inRect);
Rect operator=(const Rect inRect);
Rect operator=(const CGRect inRect);
.
.
.
};
I wanted to extend it to allow easy initialization from NSRect as well, so I
added appropriate methods:
#if __OBJC__
Rect(const NSRect inRect);
Rect operator=(const NSRect inRect);
#endif
But I get a compiler error on these lines:
Rect.h:61: error: 'Graphics::Rect::Rect(const NSRect)' cannot be overloaded
Rect.h:59: error: with 'Graphics::Rect::Rect(const CGRect)'
I'm not sure why this should be the case.
Any help is much appreciated!

Hey! Look at that! Under certain conditions, NSRect is just typedef to be
CGRect (as it should've been all along).
Sorry for the noise.

Re: constructor cannot be overloaded?
Oh, and looks like it's not the first time I've asked this question.
Terrifying, since I didn't even have a vague sense of deja vu when looking at
it.
