Bug#297565: eboard: FTBFS (amd64/gcc-4.0): cast from 'Board*' to 'unsigned int' loses precision

[Andreas Jochens]

Package: eboard
Severity: normal
Tags: patch

When building 'eboard' on amd64 with gcc-4.0,
I get the following error:

g++ -O2 -I/usr/include/gtk-1.2 -I/usr/include/glib-1.2 -I/usr/lib/glib/include 
-I/usr/X11R6/include -c board.cc -o board.o
board.cc: In member function 'void Board::dump()':
board.cc:1062: error: cast from 'Board*' to 'unsigned int' loses precision
board.cc:1063: error: cast from 'ChessGame*' to 'unsigned int' loses precision
make[1]: *** [board.o] Error 1
make[1]: Leaving directory `/eboard-0.9.5'
make: *** [build-stamp] Error 2

With the attached patch 'eboard' can be compiled
on amd64 using gcc-4.0.

Regards
Andreas Jochens
