Well, I just tried it on the August 11 snapshot. So unless you put in a patch
over the night, it still issues those warnings.

I could do that, and I thought about it; (sprintf(buff, args)) instead of
snprintf because I want to remain compatible on systems that do not have
glibc. But I was hoping to make the code easier to read by keeping that
'format' variable in there. Again, the only time I get that warning is when
there are two tokens with string concatenation ("abc" "def", args...). GCC
didn't complain about this before, so I was wondering if it could get fixed.

Thanks.
