 // Support for alternative bool type. This is only enabled if the code is
 // compiled with USE_MYBOOL defined. This catches some nasty type bugs.
 // For instance, 'bool b = "false";' results in b == true! This is a hidden
 // source of bugs.
 // However, redefining the bool type does have some negative impact on some
 // platforms. It gives rise to compiler warnings (i.e. with
 // MSVC) in the API header files when mixing code that uses the standard
 // bool with code that uses the redefined version.
 // This does not actually belong in the platform code, but needs to be
