You mean make will not compare the timestamp of .c and .o file?

Apparently not, you should run "rm -f <filename>.o" firstly, then "make
<filename>.o"
Maybe you can write a script to do this if you want to.

If .o file is not cleaned, make will automatically select the changed files
to compile and link?
