 64bit atomic ops on 32bit arm? How does that happen?

 Let me rephrase: I think it is a bug in the pkg providing <xmlrpc-c/server.h>,
 whichever that is, and it should be patched in pkgsrc.

 On NetBSD we have a nice __HAVE_ATOMIC64_OPS define to guard cases like
 this.

 Thanks Martin for pointing out! Please be free to reassign this to pkgsrc-bugs
 and let's see if I (or someone else) can find fix for rtorrent and/or
 xmlrpc-c for this.

 Actually, earm has 64-bit atomic ops.  arm does not since it doesn't =
 guarantee=20
 8-byte alignment.=

 Indeed, and in -current we provide the symbols - I need to collect and
 submit a pullup request, sorry for the confusion.
