Subject: [PATCH] Push the atime and mtime of generated Makefile.PLs back 4
 seconds in make_ext.pl

In certain circumstances ( on virtual machines ) the generated Makefile.PL can
produce a Makefile that is older than the Makefile.PL

Altering the atime and mtime backwards by 4 seconds seems to resolve the issue.
