parallel netcdf version info

[Jim Edwards]

Hi Rob,

Happy New Year!   While you are looking into that I've found another issue
in configure I wonder if you could look into...

In configure.in at around  line 429 is some code that converts comments in
pnetcdf.inc from c-style to fortran-style, this code does not get reproduced
in config.status - so if you run config.status it ends up corrupting the
pnetcdf.inc file.

Also - to complete the F90 interface I need to modify the *.c files in the
src/libf directory.   These files have a header line that states:

This file is automatically generated by buildiface -infile=../lib/pnetcdf.h
> -deffile=defs

but I cannot find the program buildiface in the repository?

- Jim
