* This file should only contain preprocessor commands so that
* there are no dependencies on other files.

/*!
* Uniform names are defined for compile time options to distinguish
* CPU types and Operating systems.
* Distinctions between CPU and OpSys should be orthogonal.
*
* These uniform names have initially been defined by keying off the
* makefile/build names defined for builds in the OpenGL group.
* Getting the uniform names defined for other builds may require
* different qualifications.
*
* The file is placed here to allow for the possibility of all driver
* components using the same naming convention for conditional compilation.

*
* ...some compilers can give you a warning telling you that you screwed up.
* The compiler can also give you a warning if you forget to #include
* "cpuopsys.h" in your code before the point where you try to use these
* conditionals.
*
* Also, the names have been prefixed in more cases with "CPU" or "OS" for
* increased clarity. You can tell the names apart from the old ones because
* they all use "_IS_" in the name.
*
* Finally, these can be used in "if" statements and not just in #if's. For
* example:
*
* if (NVCPU_IS_BIG_ENDIAN) x = Swap32(x);
