This is problem with compilation environment that
is fixed in later versions ... works fine on Digital UNIX 4.0.

If you can't upgrade,
try replacing the value of the constant X_FLOAT_MAX in src/libsrc/ncx.h
with the value of FLT_MAX from /usr/include/limits.h. (It should be
close to the same value.)

There may be a couple of other places where you have to do the
same thing. nc_test and nf_test try to test out to the boundary
value but don't share the private include file ncx.h.
