as targets. This caused problems because some directories were missed and mult-
iple directories were being processed simulatenously. Directories are not hit one
at a time using "for" loops. Also, a common set of suffix rules in now in
macros/suffix
and "make" instructions for the sub-directories are now read from
macros/subdir.targets
NOTE: the make system in the new macros module is not compatible with the
old make system. To rebuild, you must update all modules.
