Package: make
Version: 3.81-5
Severity: normal
I believe that when a new soft link is made to an old file, make
is checking the age of the resolved path (i.e. the old file), not the
age of the link (which is new, and may have changed).
The result is that when the dependency is expressed through a soft link
then the target may not be updated when it should be.
Problem seen when running make in /etc/mail/ for sendmail, when the
sendmail.mc file is a softlink to one of two models. The link is
changed when the laptop's configuration is changed. But make was
not updating the sendmail.cf target. Reason appeared to be that the
link target was older than sendmail.cf.

Hi,
A symbolic link is merely a substitute for the real target,
POSIX states:
Symbolic links are interpreted at run time as if the contents of the
link had been substituted into the path being followed to find a file
or directory.
This means that all the attributes of a symbolic link are
normally looked at.
Now, make allows you to override this:
`-L'
`--check-symlink-times'
On systems that support symbolic links, this option causes `make'
to consider the timestamps on any symbolic links in addition to the
timestamp on the file referenced by those links. When this option
is provided, the most recent timestamp among the file and the
symbolic links is taken as the modification time for this target
file.
