Mystery vim7 versus vim6.4 - same term, different results

Hi,

I have a mystery concerning screen display and keyboard maps. I've got
nottybuiltin set, so vim reads the external termininfo first. term is set to
xterm. OS is SunOS 5.9. TERMINFO is set to /etc/terminfo

When I use vim version 6.4 the screen displays right and the keys work
correctly, even the page down keys and such.

When I `upgrade' to 7.3 - the screen display changes, and they keymappings
change. For instance pageDown no longer behaves like ctrl-D or ctrl-B.
Instead, it moves down line line at a time, as if makked to the down arrow.

But all other variables and init files are the same. When when I example the
t_ mappings, with set termcap ? -- the maps appear to be identical. Yet the
screen and keys behave differently.

Why does version 7.3 behave differently? Iv'e tried the binary vim-7.3 from
sunfreeware, for solaris 7 9 and even 2.6 -- they all exhibit this difference.
