Summary: SIGBUS on OpenBSD/sparc64

Initial Comment:
XChangeProperty is being called for changing property _XA_NET_WM_PID passing a pointer to a *pid_t instead of the expected pointer to a *long. On my box they are 32bit and 64bit integers respectively and so the application crashes because of an unaligned access.

See this bug report on the OpenBSD bugtracker for further details: http://cvs.openbsd.org/cgi-bin/query-pr-wrapper?full=yes&numbers=6522

The following patch solves the problem:
