dnl If we're installing into a subdirectory of /usr/include, etc., we should
dnl prepend the subdirectory's name to the "#include" paths.  It won't hurt
dnl anything, and will make it more standardized.  It's awkward to decide this
dnl at configuration because of quoting, so we'll simply make all headers
dnl installed via a script that can do the right thing.
