[PATCH] __func__ and __FUNCTION__ in configure script

[Kris Katterjohn]

Hi everybody, I'm Kris.

A little background: I've been contributing to Nmap for over a year, and 
am an SoC student for it this summer.


But on to the patch..


Currently:

__func__ and __FUNCTION__ are checked for in the configure script, but 
if one or the other doesn't exist, it is changed in defines.h.


Patched:

They are both still checked for in configure, but this is done in the 
configure script as well:

1) If __func__ exists, it's used
2) If not, but __FUNCTION__ exists, define __func__ to __FUNCTION__
3) If neither exist, define __func__ to __FILE__

So this eliminates the need for the HAVE___func__ and HAVE___FUNCTION__ 
defines, the checking/modifying in defines.h, and it's all done in one 
spot in configure.


I implemented pretty much the same thing in Nmap, and I thought it'd be 
helpful here as well

I didn't run autoconf before I diff'd it because it probably would've 
made the patch huge.


Please CC me on any replies, as I'm not subscribed.

Thanks,
Kris Katterjohn
