Well, in two cases that I looked at, that turned out to be true.
Not sure if there were any exceptions. Maybe samba-common.
I'll pay attention in the future when I see it happen next...
I'm still not clear, though: if the file being installed is part of the
sources that's being built (i.e. it's not a generated file), and the
makefile that does the install invoked "cp --preserve=timestamps"
then both the .i386 and the .x86_64 copies should have an identical
timestamp. Right?
