__FUNCTION__ cannot concatenate with constant strings in all compilers.

__FUNCTION__ cannot concatenate with constant strings in all compilers.

According to http://www.delorie.com/gnu/docs/gcc/gcc_78.html (bottom),

    The identifier __FUNCTION__ is implicitly declared by the translator
    as if, immediately following the opening brace of each function
    definition, the declaration

    static const char __FUNCTION__[] = "function-name";

So use an explicit << instead of relying on string constant concatenation.
