One of the purposes of FSF GCC development is to get more people to use
GCC.  That's more likely to happen if we make GCC work well for them.

We should not try so hard to be consistent that we do the wrong thing.
It's good to have procedures and rules, but not to the point that they
are absolutes.  Decisions about these kinds of things are of necessity
only semi-algorithmic.

This isn't like a -f option which is a documented feature.  This is the
current behavior of the compiler, which I expect you'd find most people
consider to be odd, despite the fact that there is some utility in the
current approach.

I think it would be wrong to make this change now (it's clearly neither
Stage 3 nor regression-only material), but I see no reason not to make
it in 4.2.

Sure, filing OS bug reports is good.  It's just orthogonal; we still
have to build software that works with the systems users are using.
