The "-O2" flag should be separated from the threading support. Besides, it belongs to CCFLAGS (compile flags common to C and C++), not to CPPFLAGS (preprocessor flags). While at that, enable all warnings by -Wall, except those about non-virtual destructors, which are "inherited" from Qt. Portability is not affected since -O2 was already gcc-specific.
