[cfe-dev] CompilerInstance as CPP compiler?

[Hendrik vP]

Either your adding the "-x c++"-option to your compilercreateion, or, by
code, you can take the language-options of the compiler and set the
appropriate flags by yourself
LangOptions lopts= compiler.getLangOptions(); (
http://clang.llvm.org/doxygen/classclang_1_1LangOptions.html)
