feel free to use it. I never store anywhere other than stackoverflow.
Attached the current version, I don't rememeber if I changed
it in the meantime.

Attached another that you can find useful
it uses cygcheck and binutils to provide the list of first level
packages containing the needed DLL's

$ cyg-dependency.sh /usr/bin/octave-5.2.0.exe
/usr/bin/cygwin1.dll  =>  cygwin-3.1.7-1
/usr/bin/cygX11-6.dll  =>  libX11_6-1.7.0-1
/usr/bin/cyggcc_s-seh-1.dll  =>  libgcc1-10.2.0-1
/usr/bin/cygstdc++-6.dll  =>  libstdc++6-10.2.0-1
KERNEL32.dll  =>   Windows System

I found useful to avoid some screwup

Marco
