--- Comment #9 from Igor Gnatenko  ---
* use gcc-c++ for building (add `gcc` into `%make_build` line)
* replace CFLAGS with CXXFLAGS
* it still ignores CXXFLAGS (Makefile needs patching)
* verbose compilation is not enabled (I mean to show what and how has been
executed). Remove `@` in lines like `@$(LEX)`, `@$(CXX)`, etc.
* Trailing dot is missing in description
