This is certainly because GUB uses smart-autogen.sh, which runs autogen.sh if only if stepmake/aclocal MD5 sums have changed since last smart-autogen.sh invocation. The problem is, Werner requested that make checks that configure script has a more recent modification time than configure.in and stepmake/aclocal.m4, which may happen even if MD5 sums of these files -- e.g. mtime of source files checked out from Git is the time when the file was last checked out or updated after merging/fast-forwarding/pulling. I'm reverting the change I made. To sum up, smart-autogen.sh is too smart for make, and this is one more reason to switch the build system to SCons, which Jan almost convinced me to do. John
