From 8bd2c972b1e2343620cad5b0f56de0f2524b7564 Mon Sep 17 00:00:00 2001 From: Reuben Hawkins Date: Thu, 8 Jan 2015 12:00:55 -0800 Subject: [PATCH] configure.ac: check 'tv_nsec' field in 'struct stat' Detect 'tv_nsec' field in 'struct stat' and set Makefile variable NO_NSEC appropriately. A side-effect of the above detection is that we also determine whether 'stat.st_mtimespec' is available, so, as a bonus, set the Makefile variable USE_ST_TIMESPEC, as well.
