In newer distros (ubuntu 15.10, fedora rawhide) the binutils ar uses the new D flag per default to build deterministic binaries. Without this patch the following warning is issued, when building btrfs-progs: [AR] libbtrfs.a /usr/bin/ar: `u' modifier ignored since `D' is the default (see `U') For libtrfs.a performance benefit of the u option can be neglected, so drop the u option and silence the warning. In the future one might want to explicitly add the D option anyway. Signed-off-by: Arnd Hannemann <arnd@arndnet.de> --- Makefile.in | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
