While I completely agree that I'd prefer to have full (and auto-generated) dependencies between .c and .h files in the makefile, the build infrastructure has many more "incorrect" parts than that and I doubt we will ever have a "correct" solution. There is always a tradeoff between convenience and excessive recompilation. Stefan PS: examples that I have bumped into over the last few months: - modifying an elisp macro will not automatically force a rebuild of all the .el files that make use of it. - changing from `make' to `make CFLAGS=-DENABLE_CHECKING' does not force recompilation of the .o files. - modifying `Makefile.in' will correctly cause rebuilding of `Makefile' but will fail to reconstruct the targets that the Makefile describes. - upgrading libc will not automatically cause `configure' to be rerun. - deinstalling libpng does not automatically cause `configure' to be rerun.
