Unfortunately, the person who wrote the "ncx.c" module is no longer with
us. Looking over the code, however, it appears that the module can be
compiled on an SX system only if the C macro _FLOAT2 is also defined. I
don't know how that macro would be defined, however. I suspect that some
compiler option would set it.

Our support-email archive has the following email from the developer of
the ncx.c module:

    http://www.unidata.ucar.edu/cgi-bin/msgout?/glimpse/netcdf/2687

The _FLOAT2 macro is mentioned in it.  Unfortunately, I've never worked
on an SX system, so I don't completely understand the email.  You might
have better luck.

Sorry to be of so little help.  Things might be different if we had
access to an SX system.

Good luck.  If you think we can be of further help, please don't
hesitate to contact us.
