     If a native (i.e. supported directly by the compiler) 64 bit integer type was
     found to exist, @e wxLongLong_t macro will be defined to correspond to it.
     Also, in this case only, two additional macros will be defined:
-    wxLongLongFmtSpec() for printing 64 bit integers
-    using the standard @c printf() function (but see also
-    wxLongLong::ToString for a more portable solution) and
-    wxLL() for defining 64 bit integer compile-time constants.
