Yep, just downloaded qcad-2.0.5.0-1-community.src.tar.gz and I get:

$ cd scripts
$ QMAKESPEC=/usr/share/qt3/mkspecs/linux-g++ QTDIR=/usr/share/qt3 ./build_qcad.sh

The change needed is in:

qcad-2.0.5.0-1-community.src/mkspecs/defs.pro:

QMAKE_CXXFLAGS_DEBUG += -pedantic
QMAKE_CXXFLAGS += -pedantic

just comment out those 2 lines and it should build fine.
