as GraphicsMagick 1.3.21 is pumping C++ ABI,

   /usr/bin/cygGraphicsMagickWand-2.dll

in 3 packages

libGraphicsMagick3
   /usr/bin/cygGraphicsMagick-3.dll

Underscores should be added only when there are two consecutive but
separate numbers (e.g. libglib2.0_0, where 2.0 is an API version and 0
the ABI version, or libhdf5_9, where the 5 is part of the library name
itself).  That doesn't apply here, so:

I will use "-" as done on netcdf

libGraphicsMagick-cxx11
  /usr/bin/cygGraphicsMagick++-11.dll


libGraphicsMagick-Wand2
   /usr/bin/cygGraphicsMagickWand-2.dll

Question:
Other than octave there is any other package depending from
C++ interface cygGraphicsMagick++-3.dll ?

It should be none in cygwin, but eventually pdf2djvu in cygport ?

Correct on both counts.

Ok, I will upload a a 1.3.20-2 with splitted libs
so you can just point to

libGraphicsMagick-cxx3
  /usr/bin/cygGraphicsMagick++-3.dll

as pdf2djvu dependency until rebuild.

While we are at it, I am concerned about a similar issue arising with
the ImageMagick libraries.  IMO they should be broken up into
libMagickCore6_2 (which would OBSOLETES libMagickCore6),
libMagickWand6_2, and libMagick++6_5 packages.  In the case of both
packages, however, I would leave the single -devel for each as is.

I will consider on next rebuild.
Anyway ImageMagick breaks so many times the API/ABI, that next build will surely require something different from today.
