There is a patch to fix this on Wine's Bugzilla and you have to download the source for ld from opensource.apple.com. I told him about that. > Also, there is very little truth to the fact that running X86 processors in 64 bit mode disables v86 mode. I could swear that you couldn't enter v86 mode when in 64-bit mode. I seem to remember reading something about that in an early x64 manual I had. > Maybe Apple disabled this in Snow Leopard, but Vista 64 supports running Win16 programs. That's because you don't need v86 to run most Win16 programs; they run in 16-bit protected mode (which IS supported even in 64-bit mode). Chip
