Log Message:
Stop mangling __func__ for C++11 and newer

Drop local logic between GCC 2.4 and GCC 2.6 that used __PRETTY_FUNCTION__.
This caused __func__ to be redefined for all C++ programs and use a
different behavior than intended by the compiler (Clang and GCC).
__PRETTY_FUNCTION__ prints all the prototype not just function name,
contrary to __FUNCTION__ and __func__.

__func__ is now an integral part of C99 and C++11, shipped by a compiler.

This change aligns the behavior of C++ programs using __func__ to other
Operating Systems. The difference caused unnecessary fallout in regression
test suites in projects (LLVM, fish, ...).
