Preprocessor - Cross Platform

[Miquella]

I'm currently developing a program that needs to be cross-platform, but some of my abstraction layer needs to be platform specific. I know that there are some Preprocessors that work on certain systems, but I'm wondering if there are standards for such things?

I'm currently using things such as:

_WIN32
__WIN__
__UNIX__
__APPLE__

But I know that these are not always constant, and some not even prevalent, but is there a better way to do this??

Thanks for your help!

These are normally set by some makefile somewhere. Very often they are not even built into the compiler. There is no standard as far as I know.

Have a look at the sources for FLTK in

http://www.fltk.org/.

It supports the same platforms.
