This usually only happens if some very basic package
file has changed. For instance, if your branch uses a
different GCC version than master, this might easily
happen.

Having that said, if you switch branches, only those
packages should be rebuilt which have been changed over
the branches (and also their dependent packages, of course).
Otherwise, it's a bug.

If you think your branch diverged too much from master,
you might want to merge it, or even better: to rebase
it on master.

    git checkout my_branch
    git rebase master

Also, I recommend to check your branches before and
after each suck operation via:

    git show-branch

Or, if the above command shows too many branches:

    git show-branch master my_branch

If you think this is really a bug (i.e. MXE rebuilds more
than what was changed), please provide a short, but detailed
description so others can reproduce the bug.

It's not just me, it's also GitHub forcing you to use
branches for pull requests. :-)
