I don't know that it's relevant to your problem, but you should
seriously consider using the simply expanded (immediate) type of
variable and not recursive (deferred) expansion.  This means using ":="
and not "=" to assign values.  With deferred expansion the shell
commands will be (re-)run every single time those variables are
referenced in a rule or expanded in another variable, which could
potentially be very costly (and not what you intended.)
