The gcc-4.5 toolchain rebuild is in [testing].  Here is a summary of the 
changes I made:

   update patch level

   patch for gcc-4.5 __i686 define/assembly clash

   rebuild libiberty/libbfd on both platforms
   hide symbols in libbfd

   upstream update
   add new deps (libmpc, libelf)
   enable link time optimization
   tidy up configure
   add c89 and c99 launcher scripts (POSIX compatibility)

Unlike the last couple of gcc releases, this should be a relatively 
minor update in terms of breakages.  See 
http://gcc.gnu.org/gcc-4.5/changes.html .

As is usual with gcc updates, compiling C++ code with the new toolchain 
and running it with the old toolchain may cause some issues (untested) 
so be careful.

Signoff both,
