Subject:	Porting Dflat++ to DJGPP

I looked at Dflat++ and tried to port it.  It won't.  The reason
is that it relies heavily on pointer to member functions, in
particular casts of pointer to member functions.  Unfortunately,
the G++ pointer-to-member code is broken in version 2.5.7.
These are some of the same bugs that cause Fresco (part of X11R6)
not to compile with the current G++ under UNIX.  Supposedly this
has all been fixed and casts of pointers to members will work with
the next version of GCC/G++.

Dflat++ uses ptrs to member functions for all the menu-activated
commands.  I do the same in my code but I use a gross hack to work
around these bugs, but it requires declaring *all* function you
ever want to use in any menu in a class way, way up on the
inheritance hierarchy, as high as the highest menu-function you
ever use.  Doing this with Dflat++ would seriously lobotomize it.

Oh well...
