Follow-up Comment #4, bug #57281 (project octave):

If you want to build both stable and default frequently, I recommend usin
separate source trees for the default and stable branches.  That minimizes
time-stamp changes when switching from one to the other.

Also, although it is possible, I recommend using a build tree that is separate
from the source tree.

If you frequently build after updating, ccache will also speed things up a
lot.

However, if you do attempt to build in the source tree and switch between
branches, you should probably do


make maintainer-clean
hg update BRANCH
./configure ...
make


Otherwise, you will run into problems with stale files left over from previous
builds.
