OT: Warning message when doing make -f Makefile.cvs

[Dawit A.]

Hello,

Can any kind soul, please tell me what the following error message means ?
I have the exact same autoconf and automake packages installed on both a 
Mandrake 8.1 machine and a redhat 7.1 machine.  I only get this warning 
message on the Mandrake box and was curious as to the cause.  I could not 
find any reference to a similar question in the archives ; so I cannot tell 
if this has been asked before...

make -f Makefile.cvs
This Makefile is only for the CVS repository
This will be deleted before making the distribution
