Hi Mark,
yes I am aware.
It is the inconvenient of using fortran module with a rolling
  distribution like cygwin. Any time the compiler major version
is updated, I need to rebuild netcdf-fortran
(that is the only package using fortran modules for what I know)

The 64 bit chain is ready, I am also upgrading to latest version

hdf5 		1.8.13-1 -> 1.8.14-1 (abi bump)
netcdf 		4.3.2-2  -> 4.3.3rc3-1
netcdf-cxx4	4.2.1-2	 -> 4.2.1-3
netcdf-fortran	4.2-4    -> 4.4.1-1

as soon the 32bit chain is completed, I will update all.
Possibly today or tomorrow

Regards
Marco
