[netCDF #BVS-485205]: Ticket ID: GLX-497823

Hi,

It looks like the problem with

> Undefined symbols for architecture x86_64:
> "_iargc_", referenced from:
> _MAIN__ in wrf_to_gmt.o
> ld: symbol(s) not found for architecture x86_64

actually means what it says, that the iargc intrinsic function from Fortran-77 
is no longer
supported by gfortran.   I thought it was a more general problem of gfortran 
version
not matching gcc, but that was wrong.

It looks like for portability you'll have to either use the new Fortran 2003 
function
COMMAND_ARGUMENT_COUNT(), or make sure you aren't declaring IARGC as an 
extrinsic function:

Sorry about the bad advice ...
