[plug] overriding default c++ compiler

[Craig Ringer]

Hi all

I've been bashing my head against a wall here with no success - how do I 
override the default C++ compiler that make, configure etc will use? I 
seem to remember that there's an environment variable for it much like 
CC is for straight C .

A link to a "c/c++ on unix: total newbie's guide" would be really cool 
if anybody has one, since I didn't find anything on google (somehow).

Thanks
