I wondered whether the 3x increase with --enable-checking=all was a nativecomp phenomenon, but it seems to be the same without nativecomp. It takes 2:30 to built the trunk with just ./configure, and about 8 minutes with checking. I tried the same in emacs-28, and it's much the same story there: Without checking, it's 2:20, and with checking it's 6:50. So it's not a new phenomenon that checking adds a multiplier to the build time, but it seems to be worsening somewhat. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
