I think the errors are because the Pentiumized gcc doesn't support
the "A" constraint. It is based on an ancient version of gcc (2.3.x
or 2.4.x) and doesn't support all the features of 2.6.x or 2.7.x.

Real fix: compile all files with the standard cc (2.6.3 + FreeBSD patches).

Responsible-Changed-Why:
The pgcc port is maintained by Andreas.
As Bruce pointed out, pgcc is a hybrid of gcc-2.4.X and gcc-2.7.X,
and our kernel uses backend features not present in 2.4.x. This is a
pgcc bug, not a kernel problem.
The warnings are part of gcc-2.7's more picky frontend.

This is caused by FreeBSD's std*.h not actually being standard (rune_t isn't
standard), and gcc's stddef.h being out of date.

Real fix: use the standard headers.

State-Changed-Why:
argh, I was trying to abort the last state change but gnats
went onwards.. :-(
What I meant to say was that the pgcc port is probably rather
broken in other ways too, since it doesn't appear to have the correct
config/i386/freebsd.h file, as well as a whole host of other fixes.
And besides, the standard headers are meant to be used with gcc, it
should not supply it's own. This is a problem with the port.
