Comment 7 for bug 185263

If it's an upstream problem (as Tollef said, "Not only would you need a different libc, you would have to have _all_ other libraries compiled with this same other ABI. I suspect you would have to get support into the kernel as well for it."), where's the best place to start filing wishlist bugs for it? The gcc bugzilla? The glibc bugzilla? The kernel bugzilla? Is this entirely impossible without hardware support from Intel and AMD? (Given that the request is simply for the option to compile some applications to use 32-bit pointers and be restricted to 4GB of address space, perhaps the problem can be solved at the virtual memory level rather than requiring specialized hardware?)
