Not all OSes use st_ctim and st_mtim in their struct stat. In particular, it appears that OS X uses st_*timespec instead. So add a Makefile variable and #define called USE_ST_TIMESPEC to switch the USE_NSEC defines to use st_*timespec. This also turns it on by default for OS X (Darwin) machines. Likely this is a sane default for other BSD kernels as well, but I don't have any to test that assumption on. Signed-off-by: Brian Gernhardt <redacted> --- This is on top of "next". Now time to go debug a Bus Error in git-grep that made this hard to find. Makefile | 7 +++++++ git-compat-util.h | 5 +++++ 2 files changed, 12 insertions(+), 0 deletions(-)
