Notes:
Make variable replacements open a can of worms. Sometimes they should
be quoted and sometimes not. Sometimes their replacement values are
already quoted.
VS variables cause problems. In order to pass the referenced value
with spaces the reference must be quoted. If the variable value ends
in a backslash then it will escape the ending quote! In order to make
the ending backslash appear we need this:
"$(InputDir)\"
However if there is not a trailing backslash then this will put a
quote in the value so we need:
"$(InputDir)"
Make variable references are platform specific so we should probably
just NOT quote them and let the listfile author deal with it.
