This patch is a little hack to make qcad-2.0.5.0-1-community build with recent
gcc releases and install cleanly in /opt/qcad.

Usage:
- extract qcad-2.0.5.0-1-community.src.tar.gz
- cd qcad-2.0.5.0-1-community
- patch -p0 < qcad-2.0.5.0-1-build.patch
- cd scripts
- sh build_qcad.sh noprepare notrans
- sh install.sh
- add /opt/qcad/bin to your PATH
