Let's not worry much about that. In practice, little development of
Automake-using software occurs on FAT file systems, and even if it did those
file systems are low priority for GNU development.
I just checked, and GNU Make uses high-resolution file timestamps when
available, and considers a file to be up-to-date if it has exactly the same
timestamp as its dependency. I suspect that this is because Makefile rules like
this:
a: b
cp -p b a
would otherwise cause needless work if one ran 'make; make'.
If Automake followed the same rule as GNU Make, we'd at least have the benefit
of consistency....
