When building '3dwm' with gcc-3.4 I get the following error:
c++ -DHAVE_CONFIG_H -I. -I. -I../../include -I../../include/Celsius -Wall -Wp,-MD,.deps/Matrix3D.pp -c Matrix3D.cc -fPIC -DPIC -o .libs/Matrix3D.lo
In file included from ../../include/Celsius/Matrix3D.hh:41,
from Matrix3D.cc:36:
../../include/Celsius/Math.hh:50: error: `Math::tolerance' cannot appear in a constant-expression
../../include/Celsius/Math.hh:56: error: `Math::pi' cannot appear in a constant-expression
../../include/Celsius/Math.hh:57: error: `Math::pi' cannot appear in a constant-expression
make[4]: *** [Matrix3D.lo] Error 1
make[4]: Leaving directory `/3dwm-0.3.1/src/Celsius'
With the attached patch '3dwm' can be compiled using gcc-3.4.

3dwm has been removed from Debian unstable because it is no longer
maintained upstream and (apparently) not used. Yeah,
http://www.3dwm.org just times out...
