current_function.hpp doesn't include Intel C++ where __FUNCTION__ can be
used. It is more-less equivalent of GCC __FUNCTION__ (not the pretty one).

No other similar macro works. It is not listed in official documentation but
(likely) provided as GCC compatibility feature.

Tested configurations:
- Intel C++ 6.0 plugin in MSVC 6
- Intel C++ 7.0 plugin in MSVC 6
- Intel C++ 7.0 standalone

(Number of configurations is much larger, including Linux version).

Btw: what is purpose of  current_function_helper()?
