a question to warnings from make

[Helmut Dipper]

Hello,

I only have a question to warnings from make:

There is a file-tree on machine "phosphat" (platform SunOS)
and a make, after a "all-clean", running on machine "pollux" 
(platform Linux) to make "all" for this file-tree.
During the make I got a number of warnings like:
make[5]: *** Warning: File `../lib/gaa.cdb.de.idx' has modification time in the
future (2002-02-19 13:58:37 > 2002-02-19 13:58:35)
make[5]: warning:  Clock skew detected.  Your build may be incomplete.

What can I do to avoid those warnings?

The clocks of both machines are synchronized daily with a 
difference lower than one minute.

make --version delivers:
pollux 1: make --version
GNU Make version 3.79.1, by Richard Stallman and Roland McGrath.
Built for i686-pc-linux-gnu

Thanks for Your help.

Best regards
Helmut Dipper
