    linkat: wrap to handle symlinks on OS X 10.10 · c8e57ce5

    * m4/linkat.m4 (gl_FUNC_LINKAT): linkat() is available on Yosemite
    but not usable because it doesn't support creating hardlinks
    to symlinks.  Therefore add a generic test for this capability
    and fallback to our emulation if linkat() fails with ENOTSUP.
