Estimated hours taken: 1 Ensure that mmake does not attempt to remake the `.c' file if it is up-to-date. (This change should hopefully fix a problem with the source distribution not being able to bootstrap itself.) Also a couple of minor tidy-ups. scripts/mmake.in: Export new variable MMAKE_MAKE_CMD, for use by Mmake.rules. scripts/Mmake.rules: In the rule for `.m' -> `.o', use a recursive invocatino of make (via the MMAKE_MAKE_CMD variable) to build the `.c' file, rather than unconditionally invoking `$(MCG)'. scripts/.cvsignore: Add Mmake.vars, since it is now automatically-generated. scripts/ml.in: Some stylistic changes: make sure that autoconf @var@ variables occur only in assignments to shell variables at the start of the script, not scattered throughout the body of the script.
