From http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=288535, for Sound Juicer
but the original code is in nautilus-cd-burner:

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

transport.hxx: In constructor 'Scsi_Command::Scsi_Command(void*)':
transport.hxx:87: error: cast from 'void*' to 'int' loses precision

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

Regards
Andreas Jochens
