You can do either.  There should be no conflicts either way.  All of the
1.16 files should be overwritten by the 1.18 versions in any case.

The 'clean' options just tidy up the build tree, but alternatively, it
is safe simply to delete the whole build tree after installing.

You are right that there is no 'uninstall' option, and perhaps there
should be.  If you want to delete an older version of nhc98, here are
the places that installed files live:

    prefix=/usr/local	(usually)
    $prefix/bin/
    $prefix/lib/nhc98
    $prefix/lib/hmake
    $prefix/include/nhc98
    $prefix/man/man1
    $prefix/doc/nhc98

A good idea.
