make 3.79.1, Solaris 2.6, spurious Timestamp, mod time warnings

[Phil S]

With GNU make 3.79.1 on Solaris 2.6 (sparc) I get spurious warnings about

        (1) make: *** Warning: File `blah.c' has modification time in the 
future (1969-12-31 16:59:59.999999999 > 2000-10-05 13:35:34.7479164)

        (2) make: something.c: Timestamp out of range; substituting 1969-12-31 
16:59:59.999999999

where the files blah.c and something.c have modification times within
the last year.

Admittedly, in the past sometimes I've suspected poorly synchronized
NFS caching of causing problems like this on an intermittent basis,
but these symptoms occur too frequently.

FWIW, I don't recall getting messages like this with GNU make 3.79

Looking over earlier traffic on this list, would a good workaround for
now be something like:

        ./configure --disable-nsec-timestamps
