description:
On VAX, feeding a base "NaN" to nawk causes nawk to core dump since
it tries to interpret it as a number, which causes an FP exception.
Fix this by replacing "NaN" with "*NaN*" which hides the problem.
This makes perl Configure and build correctly on NetBSD-2.0/vax.  Fix
provided by John Klos in private email.
