Description:

Make 3.82 performs many excessive stat() system calls resulting in a reduced performance. This bug is discussed here:

http://lists.gnu.org/archive/html/bug-make/2011-09/msg00025.html

along with a patch retrieved from CVS version. Could this patch be applied to Arch's make package?

Steps to reproduce:

'strace -c' a make of a medium project. There's often a tenfold increase in stat() system calls resulting in a lowered performance, especially in case of some type of network file systems.
This task depends upon
