Hi Rene, It works on my compiler. Using C. I think the -Wconversion feature was busted (perhaps still is busted) for C++. I vaguely recall that someone (one of the developers of GCC itself) mentioned that before, on this forum. And that there was a bug filed on it already. Try GCC 4.2.3, or if you are in a daring mood GCC 4.3.0. HTH, --Eljay
