It is solved in the (upcoming) 3.1 version.  Unfortunately, the
implementation as of now breaks on too many non-Linux OS's (including,
but not necessarily limited to: *BSD, Solaris, HP-UX) to port it (back)
to the 3.0 branch.

Of course, if you take a snapshot off the CVS trunk of GCC (i.e., that
what will become 3.1 in time) you're on your own (voids your warranty
and all that).  That said, it might be useful to try to see if it really
works for you.
