The C99 standard defines an implicit variable inside of each function:

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

Even though this is not part of standard C++, it is likely that C++
compilers will support this if the 'corresponding' C compiler supports
it. If so, it might be useful to support it in the ABI.

Proposal: The sequence number of __func__ is 0.

Of course, there is always discussion what the value of __func__ is in
C++ context; I think this does not necessarily need to be defined by
the ABI (or the question whether __func__ is defined at all - if it is
not used in a function, it does not matter).
