Will this solution be satisfactory for you?  That is, when invoked
with the -interpreter=mi<N> command-line switch, GDB will print the
last stable version of the MI protocol it supports.  This is actually
the way many protocol negotiations start, and I don't see why we
shouldn't behave the same.

Note that a front end which wants to support older GDB versions will
need to have a database of MI versions referenced by GDB versions,
because the old GDB versions will not print the MI version.

Are there any disadvantages to this solution?
