First things first: You are doing "make" before "make install", yes?
Otherwise you are depending on the whim of the Makefile author for exactly
what happens.

Short answer:  Add ".PHONY: install" to the makefile

Long answer: make sees the INSTALL directory, and concludes that it is up to
date, since it has no dependencies. You've just been bitten my Windows'
case-insensitivity.
