Yes, we realize that there are no guarantees, and that things may break.
That doesn't mean GCC should make drastic rules rejecting plugins that don't
match exactly.
for us to be able to ship the same plugin for all versions of Fedora Core X,
or Debian X, rather than tie it so tightly to a particular minor version.
It's very likely you could ship the same plugin sources, which would then
need to be built to separate binaries for each different GCC version.
Building the plugin requires having the GCC sources, not just the plugin
sources. GCC sources don't normally come with distros, so you have to go
through fairly complicated hoops to get the GCC sources which match the
binaries installed on your system.
