It seems when someone tries to install XBoard from source on a 64-bit system,
the 'make' process results in lots of warnings (args.h, selfile.c, draw.c)
of a type
that indeed looks quite lethal: "cast from pointer to integer of different
size".
I guess the current XBoard code is not suitable for compiling as 64-bit
application.
But apparently we fail to tell the compiler that in our Makefile.
The quick fix would be to include such a flag. (Does anyone know what it is?)
In the longer run we sould have to clean up the code with respect to
pointer <-> int
conversions. I cannot test anything of this, as I have no 64-bit systems.
