I'm not completely sure but afaik HPUX uses quite old xlibs. The problems also arise 
when talking to an old xfree installation on linux (3.x) and are not limited to the
Cygwin/X server.

The key AltGr has different names in the different versions of X.
It is now called ISO_Level3_Shift and was formerly called Mode_switch, Alt_R and 
Meta_R. Normally this should not matter but the mapping to the modifier keys has 
some voodoo too. Pressing AltGr in a recent verio of X results in an modifier 
state of 0x80. With Mode_switch this was 0x2000. There are also installations 
where the AltGr key was mapped to modifier mod5 (the present) and some where it
mapped to mod3.

Unfortunately I have not understood this topic completely and it seems that no one
on the mailinglist has dealt with this before. But you could ask the people on 
the xfree@xfree86.org mailinglist why you can't properly work with an 4.3.0 xserver
with 3.x libs.
