That could be due to a rewrite of the EncodeBuffer/DecodeBuffer code
in 3.9.0. Interestingly, the Debian folk offers this dxpc for AMD64
for several months without any patch in that area of the code:
http://packages.debian.org/unstable/x11/dxpc

In the source I see a 32-bit bit-shifting en-/decoding working with
"unsigned int" most of the time in many places, but sometimes only
with simple type-specifiers. Maybe there's an oversight somewhere.
Without an x86_64 test machine I won't even start careful proof-reading,
however. Also, the upstream authors are encouraged to use full
type-specifiers wherever possible, e.g. "unsigned int X" instead
of "unsigned X" and "sizeof(unsigned int)" instead "sizeof(unsigned)".
