Does g++ really need to compile main, if c++ code is involved?

It doesn't matter.  As a GCC extension, you can write a global
constructor in C using __attribute__ ((constructor)), and the result
is equivalent to a C++ global constructor.  It follows that if global
constructors work at all, they will work whether main is written in C
or C++.
