CheckStructHasMember: Add support for C++ Previously if headers required to check if a struct has a member can be compiled with C++ compiler only, the check would fail because the C compiler fails. As a consequence, the result variable would be set to false, even if the struct has that particular member. Teach CHECK_STRUCT_HAS_MEMBER to accept a new optional argument LANGUAGE that allows one to explicitly set the compiler to use. The new signature is therefore: CHECK_STRUCT_HAS_MEMBER (<struct> <member> <header> <variable> [LANGUAGE <language>])
