Fortunately all of those 26 are either fixed for 3.3 or included in those 77
open PRs you mentioned.

PR9255 is a regression from 3.2 which prevents m68k targets from
compiling.

Overnight, i386-rtems, sh-rtems, and sh-rtemself wouldn't complete a
build
on the 3.3 branch.  I have updated my tree and am going to see if these
failures were fixed overnight and are repeatable on i386-elf, sh-coff,
and
sh-elf respectively.

Joal,

Try this patch.  It works on Uberbaum:

It works on the 3.3 branch and allows m68k-elf to build to completion.  
m68k-rtems and m68k-coff have not been checked with this patch.

Since it is to a common file, someone very knowledgeable will have
to review it.
