Ummm, that is exactly what I said here:-


Yes, I'm a sick puppy and browse gcc-patches too :-)

AFAICT, the new patches will not be backported to gcc-3.2.x. Someone may want
to do it by hand tho'. I find it interesting that RH apllied the simple patch
to their branch. In theory, it will slow down compiles on 64M and 128M
machines due to swapping. Or maybe this branch is only for RH's "Advanced
Server" product where the minimum RAM is probably something large.
