// The logic here depends on CMake preprocessing of the file significantly.
// If CMake has CATCH_CONFIG_FALLBACK_STRINGIFIER it will be define below,
// and its value is written into the if. Thus, we undef the old placeholder
// and then define the macro to the actual CMake-provided value.
//
// We can't do it without this indirection, because it is a string-variable
// macro, so we need it's value, and there is no usable default value that
// would let us have it always defined the way the other two are.

// Unlike the macros above, CATCH_CONFIG_FALLBACK_STRINGIFIER does not
