There is no such thing as DJGPP C++.  DJGPP is a development
environment, not a language.  :-)

However, the gcc compiler on which DJGPP is based does support a 64-bit
integer, named 'long long'.  You can use this like any other data type,
including printing and reading it.  The Allegro graphics library has an
excellent fixed-point implementation that you might want to look at.
