Works if you provide an (empty) input file:

echo | gcc -S -x c -v -

 /usr/lib/gcc/i486-linux-gnu/4.3.1/cc1 -quiet -v - -quiet -dumpbase -
-mtune=generic -auxbase - -version -o -.s

They do already via the configure options. I don't see this mentioned  
in the email though.

[...]

There's mtune, but not march. Also, most users probably don't know that.

Not here. Or perhaps one can deduce the value (how?), but that's not obvious
and not documented either.

Also that is not true for ppc:).

That is a target specific decision. Really the default is either  
decided by the target maintainers or via the configure options. I say  
we should not worry about this bug really.
