Maybe I have the wrong impression but to me it looks like the 2.95.3 compiler
in-tree now isn't realy up to it's task.

 - sparc64, sh*, arm (others?) are heavily backporting fixes from 3.1 or 
   -current to make the compiler useable (which didn't work even for
   base system stuff for arm yet)
 - the AMD 64 bit stuff isn't supported

Are there any plans to base the in-tree version on something modern any time
soon?

Not pushing, just curious
