Is this a "make bootstrap", or is it something close yet different? > Wrote c:/Devel/emacs/repo/trunk/lisp/calendar/cal-loaddefs.el > Eager macro-expansion failure: (error "Lisp nesting exceeds > `max-lisp-eval-depth'") Of course, these may be due to simple "infinite recursion" problems fixed by bootstrapping. But they may also be due to "deep recursion", in which case increasing max-lisp-eval-depth might help (IIRC I had to bump this limit when I introduced eager macro-expansion, so it wouldn't be a big surprise if it needs to be bumped yet a bit higher). The eager macroexpansion can cause fairly deep recursion, especially if/when some of the code (e.g. macroexp.el) is not yet byte-compiled. It shouldn't be deeper than the macroexpansion done by the byte-compiler (it's basically the exact same macroexpansion in both cases), but because it happens earlier it's suffers more often of things like "macroexp.el is not yet byte-compiled". These macroexpansion failures should only be warnings, so do they prevent building Emacs? If you can reproduce them, can you try to bump max-lisp-eval-depth a bit higher to see if it solves the problem? Stefan
