When I touch one of the files and run {{{sage -b}}} I see:
{{{

What is certainly not a good idea is that the '''C''' compiler gcc is
being invoked to compile a '''C++''' program. Since option.cpp is a C++
file, it should be compiled with g++, not gcc.
I doubt that would be extensively checked by the gcc developers. It may be
a case of you get away with it on some platforms some of the time, but not
all platforms all of the time.
