Well, I can't do that because source.cpp allowed to contain #include-s.
(Of course I can parse source.cpp and create modified_source.cpp. Just
need to preprocess, then use yacc/lex or Spirit C-grammar parser...)

I can also write my own, simplified grammar parser for source.cpp (since
source.cpp is using C syntax).

But I just tried to compile with "-x c++" with extern "C" in souce.cpp
(experimentally added that manually), and when I tried to call it from
MSVC app I've got a crash.
