[Python-Dev] Where/how should I check this in?

I have a change to check in from this issue: http://bugs.python.org/issue4483 It is a build error for _dbmmodule.c which was reported against Python 3.0 involving a change to the layout of symbols in libgdbm. (There is now a libgdbm_compat in some systems which holds the dbm_* symbols.) With one tweak I'm certain needs to be applied to both 2.6 and trunk. Do I just check it in on all three branches and run svnmerge block to keep it from being considered again? Thanks, Skip
