Hi All,
All of my makefiles only compile source files and link object files that
are NEW, as in the modification timestamp is newer than OR EQUAL TO the
access timestamp, such that when I include a new source file into a project
or produce a new object file during compilation of the project, it do

What does `stat test' print respectively?

This seems to have changed as a result of this bug report:

Or, -N can be split into -A (atime > mtime) and -M (mtime > atime),
and everyone would be happy :D

That's not how Makefiles work.
Makefiles compare the mtimes of two
Hi Greg,
It is how my makefiles work :)
Do you realize how much time it takes to load the stat executable on all
source files and object files? Conditional expressions are already in
memory. I prefer using the mtime field, the atime field and conditional
expressions.

i suggest a bash only makefile script then that spawns few instances of
whatever only, i do such whatever overall systems
a find printf to comparement is fairly fast, to estimate new files
then a good gcc in one cmd
done

Sounds to me you're not using Make, but some self-made tool, so the files
you have would be more
properly called build scripts or whatever, and not makefiles.

Yeeh, that's funny indeed :)
Now this:
time ( test2Y=$(stat -c %Y test2); for (( i=0; i<1024; i++ )); do if (( $(stat
-c %Y test1) < ${test2Y} )); then echo >> /dev/null; else echo >> /dev/null; fi;
done; );

Then they aren't Makefiles. They're BaarsBuilder files or something.

What the hell.
You're writing
FILE1 -nt FILE2 True if file1 is newer than file2 (according to
modification date).
