* commit '80521c1997a23e148edf89e11b939ab8646297ca': build: allow targets to specify extra objects to link with executables swscale: avoid pointless use of compound literals libm: add fallbacks for various single-precision functions network: use getservbyport() only if available network: add fallbacks for INADDR_LOOPBACK and INET_ADDRSTRLEN Include sys/time.h before sys/resource.h Conflicts: Makefile configure libavutil/libm.h Merged-by: Michael Niedermayer <michaelni@gmx.at>
