Likewise.

The warning comes from gcc 4.2's -Wall, more specifically from -Wstrict- overflow=1 (which is part of -Wall). See: <http://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html> <http://www.airs.com/blog/archives/120> The thing being right-shifted is signed. IIRC, right-shifting of negative numbers in C is undefined. Maybe that's what the warning is getting at. -- ____________________________________________________________ Sean McBride, B.
