Folks, I am surprised that this affected the Linux emulator. Emulators should set the default FPU control word to what the native kernel would, they should not inherit this value from the one that FreeBSD assigns to its native processes. Although FreeBSD-4.0 now defaults to what Linux and Solaris expect, this should be fixed in the Linux and Solaris emulators. Because the FreeBSD control word may still be set to the old value by users and/or a dynamic scheme for FreeBSD processes may be implemented. Is a person who feels responsible for the svr4 emulator on the CC: list of this message?
