Um, rpmqv.cc compilation with g++ has been in place for several (like 5 years? I forget) years to ensure
that *.c and *.cc compiled objects can be freely linked together.

You likely can still compile rpmqv.c as C only with some straight forward Makefile.am patching,
but you’re on your own there: I wish to be able to use C++ on rpm to ensure that rpm includes and libraries
are explicitly tested as C++ ready.
