Waiting for a 2014 release is cleary not nice. IMHO we should still get
our stuff upstream, because diverting from upstream might create new
"interesting" problems. So my proposal would be:
 - upstream patches
 - get them through some basic review upstream
 - add them to our patched version when reviewed upstream

This way our patched version will:
 - not featurecreep away from upstream
 - get reviews by upstream
 - essentially be a prerelease of an upcoming make version
 - allow distros to still build with their default make by
   backporting the same patches that we do

@Michael: Did you try it again with "make -sr gb_CHECKOBJECTOWNER="
because the checks for duplicate objects create some huge strings(*).

Best,

Bjoern
