Please report any bugs that you find in this area. If you run into difficulties, then as a workaround you should be able to disable LFS by adding the `--disable-largefile' option to the `configure' script. + +On systems that support micro- and nano-second timestamp values and +where stat(2) provides this information, GNU make will use it when +comparing timestamps to get the most accurate possible result. However, +at the moment there is no system call (that I'm aware of) that will +allow you to *set* a timestamp to a micro- or nano-second granularity. +This means that "cp -p" and other similar tools (tar, etc.) cannot +exactly duplicate timestamps with micro- and nano-second granularity. +If your build system contains rules that depend on proper behavior of +tools like "cp -p", you should configure make to not use micro- and +nano-second timestamps with the --disable-nsec-timestamps flag. |
