 * wchar_t is a built-in type in standard C++ and as such is not
 * defined here when using standard C++. However, the GNU compiler
 * fixincludes utility nonetheless creates its own version of this
 * header for use by gcc and g++. In that version it adds a redundant
 * guard for __cplusplus. To avoid the creation of a gcc/g++ specific
 * header we need to include the following magic comment:
 *
 * we must use the C++ compiler's type
 *
 * The above comment should not be removed or changed until GNU
 * gcc/fixinc/inclhack.def is updated to bypass this header.
