// \file
// \brief Uniform macro definition scheme for finding out about the compiler
//
// It's much better to determine the compiler automatically here than to depend
// on command-line flags being set.
//
// Be careful when modifying this file. In general, you need to make
// sure that exactly one of the preprocessor flags is defined. For
// example, if the compiler is GCC 3.4.2, then VCL_GCC should be
// defined, VCL_GCC_3 should be defined, and VCL_GCC_34 should be
// defined. Others, like VCL_GCC_33 *should not* be defined.
//
// Note that this is most commonly implemented using a cascade of if
// statements. Be careful to add your statements to the correct place
// in the cascade list.
//
// Naming scheme:
// If you have a compiler name XYZ, then
//     #define VCL_XYZ
// Each each major release, define a release number
//     #define VCL_XYZ_4
// Avoid using the marketing name for the release number, because it's
// harder to follow. For example, Microsoft Visual C++ .NET 2003 is
// better called Visual C++ 7.
// For each minor version, define the appropriate minor version number
//     #define VCL_XYZ_40
// If necessary, define the patchlevel too:
//     #define VCL_XYZ_401
//
// Make sure that if the minor version is defined, then the release
// number and the compiler name are also defined.
//
// Add the corresponding test to tests/test_platform to make sure.
