Stefan Behlert sugested to first cast to (intptr_t) which is in
inttypes.h
http://sourceforge.net/mailarchive/message.php?msg_id=12671515
This works.

I found the wrong cast that crashed opensync:

After changing this i'm able to sync a evo2 with the file system.
osyncstress with two file-syncs gives random crashes and i'm still looking for a way to get
a backtrace in gdb.
