Peter Wemm a65dba1221 ppp-2.3.x ships with a bad compression number for deflate. It uses number
24 (which is magnalink!) rather than the correct (according to the rfc) 26.

Initial attempt at a compatability kludge that will negotiate for either
but will prefer to use the correct deflate compression type.
