Hmm.. you should have seen them since when I introduced the eager-macroexpansion, which is a bit more than 2 weeks. > Warning: Eager macro-expansion skipped due to cycle: > =CE=93=D7=90=C2=AA =3D> (load "erc-backend.el") =3D> (macroexpand-all= (defun erc-server-connect =CE=93=D7=90=C2=AA)) =3D> (macroexpand (erc-log = =CE=93=D7=90=C2=AA)) =3D> (load "erc.el") =3D> (load "erc-backend.el") [ Not sure what this =CE=93=D7=90=C2=AA is about, but I'll assume it's some= incorrect encoding of =E2=80=A6 ] > AFAICS, all of these messages are related either to loading tramp.el > or erc-backend.el. But I may have missed others, not sure. Yes, IIRC there are two such problematic cycles, one with Tramp and another with ERC (there were a couple more, but I fixed them). I'm not completely sure how best to fix them, so I preferred to leave them in and wait for the ERC and Tramp maintainers to fix them later. They're harmless in the sense that the resulting .elc files should be correct (and probably even identical). I think the warning prints a clear and concise description of the cycle, so it should not be too hard for the maintainers of those packages to understand the problem and decide how best to fix it. > and its subroutines. I never saw anything similar in "regular" byte > compilation after updating from the master repository, FWIW. A bootstrap under GNU/Linux shows those same warnings. Stefan
