That is what the current HFS module for Linux does. You get
EEXIST if you try to create 'makefile' when 'Makefile' exists in the same
directory. (which is stretching the truth only slightly). The idea of an
Extended HFS (EHFS) would involve some sort of name mangling to allow them
to coexist, perhaps making one of them something like 'MAKEFILE00001'.
