[netcdfgroup] abi version for netcdf-4.1.2

[marco atzeri <marco.atzeri@xxxxxxxxx>]

Dear Developers,
I just built netcdf-4.1.2 on cygwin, without fortran and c++ as they
are broken compared
to the previous 4.1.1, and I was surprised to see that
the outcome dll is now cygnetcdf-7.dll instead of cygnetcdf-6.dll of 4.1.1

Have you made a abi bump between 4.1.1 and 4.1.2 ? If so should be
better to change
the release number ? Between 4.1.1 and 4.1.2 I would expect minor
changes and bug fixes only.


Regards
Marco
