Since Guile is written in C, formally according to the C++ standard,
you can only load Guile from C++ code, and not the opposite. So main()
must be C++.
GCC though has integrated C and C++ fully, it seems. So you can call C+
+ from C code, but the latter do not implement C++ exception stacks,
and may not call C++ initialization function properly (I haven't
checked). It means that throwing and catching exceptions within C++
functions called from C seems to work fine, but if one tries to pass
it through a C function, the program will throw a terminate exception.
