Debian Bug #341200
selection cannot be pasted into Java applications on amd64

Atom is a 64 bit type in the amd64 architecture but, when passing
XA_ATOM arguments to XChangeProperty, one must use a "format" argument
of 32 but pass an array of 64 bit Atoms to the function.

Original issue posted and patch provided by Martin Dorey

Applied in rxvt_2.6.4-10
