Jon,

Just to verify things,
I built this on BSDI 3.0 with gcc version 2.7.2.1 without any problems.
This is on a Pentium machine of some sort. It is the closest thing I
have to your system, and frankly, I am surprised that you are having
problems. Same compiler, same cpu, pretty much the same OS, different
results? (BSDI is a Berkeley UNIX with support which has pretty much the
same roots as FreeBSD. Netcdf has been built on BSDI 2.x, which was
still binary compatible with FreeBSD?)

The only thing I can think of is gcc built improperly, or
that some include file values are hosed up, specifically the MAX_
stuff from limits.h or float.h, or DBL_EPSILON from float.h.
Another possibility is that configure is figure that you have signed
char when you don't, or vis versa.

Sorry I can't be of more help.

As I said in my previous message, I wouldn't worry too much about
failing nc_test and or nf_test in this case. The library is probably
fine.
