Compiling parallel-netcdf 0.8.9 on QSC (ASCI Q)

[Tyce Mclarty]

Can't you use the -i8 fortran flag to force 64 bit integers, so it will 
pass the configure test?

 From f90 man page:

   -i8         Makes default integer and logical variables 8-bytes long (same
               as the -integer_size 64 option).  The default is -integer_size
               32.
