a strange logical bug (PR#162)

On RH 5.2
The isnan() function returns a non-zero value if value is
"not-a-number" (NaN), and 0 otherwise.
and that non-zero is not defined!
Uh-oh...
and isnan is used in Arith.c for ISNAN and that is used in coerce.c for do_isna (why?)
is.na(0/0) # Splus compat.
So ISNAN needs to be redefined on Linux at least. Using ISNA not ISNAN solves this one for me.
But...(see above) A better fix is #define ISNAN(x) (isnan(x)!=0) Next problem: Messing with Arith.h and make'ing doesn't do anything (dependency missing, obviously)
