*all* prerequisites must be newer and not any of them when consid ering the target

[stbrice dsi]

hi all,

from the make manual
"A target is out of date if it does not exist or if it is older than *any* of the prerequisites (by comparison of last-modification times). ... so if *any* of the prerequisites changes, the contents of the existing target file are no longer necessarily valid"

is there a way to change this behavior to have:
A target is out of date if it does not exist or if it is older than *ALL* of the prerequisites (by comparison of last-modification times). ... so if *ALL* of the prerequisites changes, the contents of the existing target file are no longer necessarily valid

perhaps i've missing something (possible), but i can't find a solution to this problem.

or there's simply no solution ... :-(

thanks for any advices or links to online ressources.
