I've never seen -V used in discussions or recommendations on this list,
so here goes.
Here I use 2.95.2. A fellow admin has 2.8.1, which they need to keep for
some reason. We need to synchronize versions. Assuming that a 2.95.2
installation uses the same --prefix as the 2.8.1 installation, what's the
rule for getting them to live side-by-side?
In theory (and in the gcc.info-4 file), I know that the -V option can be
passed to the driver to override the default version. But what about all
the stuff that's outside of ..../gcc-lib/PLATFORM/VERSION? If he installs
the newer version on top of the older one, will critical stuff from 2.8.1
be zapped? What about vice versa?
I've always just distrusted the -V documentation and given each version
its own --prefix, but that's a worst case scenario here.
