Your makefile had '.\foobar:;' (a windows equivalent of './foobar:;'),
meaning the file named 'foobar' in the current directory. I thought
the special case referred to a name like '.foobar'. However, this:
  eraseme.make:5: warning: overriding commands for target `.foobar'
  eraseme.make:2: warning: ignoring old commands for target `.foobar'
  two
is what I see when I run the following makefile, so maybe I guessed wrong.

.foobar:
        echo one

.foobar:
        echo two

.PHONY: all
all: .foobar
