FWIW, assuming you're discussing PC-lint...

PC-lint considers "for (;;)" to be the "traditional" or "conventional" way 
to express an endless loop, and therefore does not comment on it.  
Personally, I use "while (1)" or "while(TRUE)" more often, and indeed, 
PC-lint warns about that, perhaps to catch mistakes of the form of "while 
(Flag)" where Flag is a preprocessor macro that expands into a constant.  To 
suppress that warning for your entire program, use -e716, or disable on the 
line you use it with a lint comment like /*lint !e716 */.
