Remove the "-O" and it compiles fine on both -CURRENT and a 4-STABLE box before the Assember / Linker upgrade. Use ``g++ -Wall'' and ``g++ -O -Wall'' on the first (that works) you are given two warnings about the code. With "-O" you only get one of the warnings (and bad linking). The only difference is in the call to to ``cpp'' in which which "-O" causes "-D__OPTIMIZE__" (use ``g++ -v'' to see this). -- -- David (obrien@FreeBSD.org) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
