When you compile a file that contains a line directive, e.g.:

from -da.
This is probably a natural consequence of the fact that cpplib got split
into a separate library. So now we need some way to communicate info
from cpp to cc1, and this is done via a line directive.
And at the least, the -fpreprocessed
documentation is wrong
when it states that this option is implicit when the file ends in .i;
this effect of -fpreprocesed
only appears when the option is actually passed to cc1.
Try "touch tmp.i; ./xgcc -B./ -v tmp.i" and note that -fpreprocessed is
passed by default to cc1. The docs aren't wrong here, you just missed
the fact that there is a hidden option in the specs.
