Well, I do not mean that other packages use "tiff/tiff.h", but the
other packages explicitly use -I<prefix>/include/tiff to locate the
stuff (see %{l_cppflags} for this). This we would have to change in all
other packages. OTOH if a package has a larger set of includes, it is
reasonable to place the stuff into its own subdir. So is a "%{l_cppflags
tiff .}" enough for Emacs to find the <prefix>/include/tiff/ files?
