And the workaround (this happens to me every few days) is:
find . -name '*.d' -exec rm -f {} \;
(in your builddir) - use at your own risk :-).

It depends on the changes made to the newly pulled code, I guess. Exactly. The most common issue is when files are renamed or deleted: without distclean, the dependency files are still there and make will fail because it thinks it still needs them. So basically: if you forget distclean and it works, then it was probably not necessary; and if build fails, you know distclean was necessary. There may have been cases where forgetting distclean would cause bugs more subtle than that, but I do not remember the specifics. Regards, Thanks for this exhaustive answer, Nicolas.
