Thank you for the resources. Those explain exactly what I am encountering.

The build environment I am using is running in a Solaris Zone on raidz2 ZFS with 6 disk devices as well as 2 disk devices configured as a ZFS mirror for boot disk.

According to the log file of "make -sr debug=t" after running "cd svx; make -r clean", the header files under $OUTDIR seemed to be re-created at the very beginning of "make -sr", e.g. 00:12:16.643938904 -- not in the process of "make -r deliverlog" -- and then a time stamp was tried to adjust to the original one, but unfortunately its resolution seemed lost during "cp -p", fstat(), or things like that in case of OpenSolaris x86.

But I am not sure, though.
