  Nope, don't worry about it, that's a bit of a red-herring.  By default, the code gcc generates is good for everything from '486
up.  The instruction scheduling and choice of which instructions to use may be tuned to be optimal for a 686 and so may be
less-than-optimal on a '586, but there should not be any actual backward-compatibility issues.

    cheers,
