The consistency is cool as ever, but I don't think LRM 10.1.4(5)
justifies anything ;-)  After all, if we put GCC x.y.z in /where/ever,
there is no problem regarding the LRM.  I will assume that it means
much more work to have a switch for system compilers, and there
might be little incentive to have two versions.

Ah, well, I have become used to switching between different
versions of compilers and interpreters.
