"mingw32-make [-j4] compile" takes: - With revno 111165 (before your changes in `lisp/makefile.w32-in'): . without "-jN": 15:57 . with -j4: 15:34 - With revno 111175: . without "-jN": 16:21 . with -j4: 6:23 A full bootstrap with "-j4" (of the last trunk) has taken 13:53. So it seems that I've got an speedup of 50% approximately. (Not bad!)
