This is a problem Cray "m4" utility.  Some possible solutions are described
on the WWW page for "Known Problems with the netCDF Distribution" at the
URL: 

    http://www.unidata.ucar.edu/packages/netcdf/known_problems.html

I've appended a text version of the relevant information from the above
document, in case you don't have access to a WWW browser.

Problem Making Fortran Jackets on CRAY Platforms

Some users have reported an error message from the m4 in building the
Fortran netCDF interface on CRAY systems:

    making `all' in directory /home/ymp8/rts/netcdf/netcdf-232pl2/fortran

            ./fortc -L . -O unicos common.inc > netcdf.inc
            ./fortc -L . -O unicos jackets.src > jackets.c

    m4:-:529 can't open file

The problem is that, at least on some CRAY systems, m4 won't accept the "-"
argument to mean read from standard input. Here are two workarounds that
CRAY sites have found successful:

   1. Manually get around the m4 problem by using a temporary file. In
     netcdf/fortran/fortc, replace the lines

             sed -f $LibDir/fortc1.sed $InFiles |
                 m4 $LibDir/common.m4 $LibDir/$OS.m4 - |
                 sed -f $LibDir/fortc2.sed

     with 

             sed -f $LibDir/fortc1.sed $InFiles > /tmp/fortcin.m4
                 m4 $LibDir/common.m4 $LibDir/$OS.m4 /tmp/fortcin.m4 |
                 sed -f $LibDir/fortc2.sed

     delete the old netcdf/fortran/jackets.c file, and rerun the "make
     all". Or

   2. Build the necessary netcdf/fortran/jackets.c file for UNICOS on a
     different platform, using the command 

         ./fortc -L . -O unicos jackets.src > jackets.c

     then copy the resulting jackets.c back to the CRAY and run make
     again. Since the modification time on this jackets.c should be later
     than on jackets.src, the fortc that invokes the Cray m4 won't be used.
