[R] make check fails for 1.3.0 on SGI at ISOdate(1901,1,1)

[Setzer.Woodrow@epamail.epa.gov]

I've successfully compiled R 1.3.0 on SGI (info below) but it fails make
check.  From base-Ex.Rout:

> ## first days of years in the (commonly used) 20th century
> seq(ISOdate(1901,1,1), ISOdate(1999,1,1), "years")
Error in if (to <= from) stop("`to' must be later than `from'") :
        missing value where logical needed
Execution halted

Indeed, from the same binary:

> ISOdate(1901,1,1)
[1] "NA"
> ISOdate(1999,1,1)
[1] "1999-01-01 07:00:00 EST"

Does anyone have any ideas?
