 * Simple testcase for compiler-specific behaviour with the defined() C++ operator
 * The spec states that if defined() appears as part of macro expansion, the behaviour is undefined
 *
 * On GNU cpp treats it as a genuine define() operator. Visual C++ doensn't.
 * This generates many warnings when compiling e.g. the BSON library under Windows
