That's the latest revision of the C++ standard.  Formerly, they used two-
digit years, but that had an obvious Y2K problem, so the new one is 0x.  
It tweaks the standard a bit in a few areas, mainly making it stricter, 
AFAIK, such that c++0x code is conformant with the earlier standard, but 
not the other way around.

gcc has the --std= directive to tell it which standard to use.

I OTOH have found _ prefixed symbols to denote internal, as opposed to 
exported symbols.  But I'm not sure whether that's common practice or 
defined somewhere.

AFAIK, Mr. Kerr is trying to find a new pan maintainer, as he doesn't 
really use news himself any more and hasn't been doing much with it at 
all.  K. Haley has sort of been doing it in the community, but has been 
reluctant to step forward and become the official maintainer.  Last I saw 
(thread on a bug, with a couple comments on the user list, AFAIK), the 
discussion was headed toward some sort of what in Gentoo would be called 
proxy maintainership -- Kerr keeping the official title, Haley (and those 
compiling from his git repo) testing the code before it goes upstream.  In 
practice that has been what's happening, but Kerr would like out of the 
position entirely if someone suitable can be found to replace him, and 
khaley has for private reasons been reluctant to be that person.  
Unfortunately, I'm not a coder myself, tho I've been around with pan for 
nearly a decade now, and do try to facilitate things on the lists to the 
best of the abilities I do have.  There was a thread on the user list 
(AFAIK) a few months ago with some details, a link to the bug where it had 
been discussed, etc.  You can check the/your archives for more if desired.
