In my reply this morning, I wrote:

It turns out that the bug is actually in the "ncgen" utility program
built with IRIX 6.2.

ncdump works fine but the ncdump test used ncgen and uncovered this
problem.  So you can use the "ncdump" you built with confidence, but the
ncgen does not properly interpret missing values, represented by "_"
when built under IRIX 6.2.  I'm looking into a fix.
