Created attachment 127702 [details, diff] librsync-0.9.7-qa.patch This patch solves the issuse (but I don't really know if it's the good way to do this).
Thanks, but such stuff really belongs upstream. FEATURES=stricter is not intended for users.
warnings are highly dependent on compiler version. this is just one of many packages that give code warnings when built. please send patches to the upstream authors.
