That's right, now I remember. I think if you change f2cFortran to 
pgiFortran in the CPPFLAGS that would work, but what I did was a bit 
different.

In the file cfortran.h in the netCDF source code, I added
#define pgiFortran
at line 129, right after the two lines that repeat
#endif /* ...Fortran */
#endif /* ...Fortran */

If you make either of the above changes, recompile netCDF, and then 
compile WRF, I think it will work.

Hope this helps,
Steve
