What this means it that ncx.c (== ncx.m4) doesn't know how to convert
your system floating point type to the external form netcdf useds.

It is basing this on what 'configure' tried to figure, which is
probably incorrect. If your alpha is like the single processor ones,
ncconfig.h should have

#undef WORDS_BIGENDIAN

#define NO_IEEE_FLOAT 1

#define SIZEOF_DOUBLE 8

#define SIZEOF_ FLOAT 4

If these values are the correct ones for your system, and configure
is saying otherwise, then we have a problem with configure.
(You can override configure manually by editing ncconfig.h).
I seem to recall that steve had to change something in configute
dealing with the 'NO_IEEE_FLOAT'. It may be that you need this
change as well, and don't have it.

If these values are _not_ the correct ones for your system, then
we may have to do some work on ncx.m4.
