Recent update of libgpg-error0 and libassuan0 break curl and Opam (OCaml package manager)

Dear Cygwin Team & Users,

I can confirm that just downgrading:

   libgpg-error0-1.47-1 -> libgpg-error0-1.37-1

and keeping the update of libassuan0:

   libassuan0-2.5.5-1   -> libassuan0-2.5.6-1

fixes the issue with curl and opam.

Since there seem to be various issues with this update of libgpg-error0, 
can we please have a roll-back?

Best regards,

Michael
