Fix alignment issue on 64-bit. Solution from Steve Ortiz.

[rsync/rsync-patches.git] / crtimes.diff

This patch adds a --crtimes (-N) option that will preserve
create times on OS X.

To use this patch, run these commands for a successful build:

    patch -p1 <patches/fileflags.diff
    patch -p1 <patches/crtimes.diff
    ./configure                      (optional if already run)
    make
