This scrip is great.

 Some questions on upstream merge process,

 1.  How to do tests to these patches.  We should apply each of these
 patches to gcc.gnu.org/svn/gcc/branches/gcc-4_4-branch, and bootstrap.
 If this patch is target-specific, shall we build a cross-compiler to
 test on target board or qemu, or build native compiler on target machine
 directly?  As Loic suggested, in ubuntu, we choose latter approach.  Any
  ARM board that we can access?

 2.  How to deal with patches for PR fix, such as  pr39429.diff
 pr41848.diff  pr43323.diff pr40133.diff, etc.  We should send updated
 patches to gcc-patches.  Shall we update gcc bugzilla accordingly? say
 "latest patch is posted somewhere in gcc-patches"

 3.  Some patches was discussed before in gcc-patches, shall we start a
 new thread on the patch discussion or go on in the old thread.

 Finally, If there is a reference that ubuntu patch goes to upstreams,
 please give me a link, that will be pretty useful for me.
