# Quirk: Inferred dependency _last_ in list when rule invoked
# -----------------------------------------------------------------------------
# NMake v3.x _appends_ the inferred dependency to the list when a rule is
# invoked. So, it is _not_ the first dependency which makes $< less usable and
# also influences the name of the target when it is derived from the first
# object. To solve this, the $* macro is used explicitly in dependency lists
# before declaring other dependencies, so it is always _first_ in the list.
