Maybe I have understood.. it seems an issue similar to that I flagged
here: https://cygwin.com/ml/cygwin/2014-12/msg00390.html
The build log shows:
Does Emacs use a png library? yes -lpng16
and ldd :
$ ldd /usr/local/emacs/bin/emacs.exe | grep png
cygpng16-16.dll => /usr/bin/cygpng16-16.dll (0x3f6700000)
cygpng15-15.dll => /usr/bin/cygpng15-15.dll (0x3f6740000)
So, the "spurious" dependency could came from ImageMagick which still
depend on libpng15.
