__FUNCTION__ and __FILE__ are C99 macros that always substitutes to the
(surprise surprise) function and file (respectively) that they are used
in. There's also __LINE__, although that doesn't seem to have bitten
you. I have no idea what C++ standard they appear in.

The easiest way to go about this would probably be to add something
along the lines of this to a header-file that's included from pretty
much everywhere:
---%<---%<---
#ifndef __FUNCTION__
# define __FUNCTION__ "__FUNCTION__"
#endif
#ifndef __FILE__
# define __FILE__ "__FILE__"
#endif
---%<---%<---

Seems like Sun Studio Pro doesn't like pure-C functions being passed as
arguments to C++ functions (or something). I'm not vell-versed enough in
Sun Studio Pro to give a more detailed analysis, but according to Google
it appears this problem shows up for more projects than nmap. Any chance
you can use the gnu tools to build this?
