Subject: [PATCH] git-count-objects: dc replacement
Johannes suggested this earlier but I did not take it so
seriously because this command is not that important. But this
probably matters on Cygwin which does not seem to come with
precompiled dc. It is a mystery for me that anything that
mimics UNIX does not offer a dc, though.
I did the detection for the lack of dc command a bit differently
from the verison Johannes did.
