We had documented the following way to build on SGI Altix:

  http://www.unidata.ucar.edu/packages/netcdf/docs/other-builds.html#altix-360

that was contributed by Len Makin and that didn't require modifying
cfortran.h.  Since someone else maintains cfortran.h, it's difficult
for us to get changes added to it, but it looks like your solution has
advantages to Makin's because it doesn't require use of flags like
-DpgiFortran that refer to other compilers that happen to use the same
Fortran to C calling conventions.

I've just added your way of doing it to that file with a link to a
patch for cfortran.h, so users can choose either solution.

If you see any corrections or would like to supply the patch in a
different form, please let me know.  Thanks for the contribution!
