I might forgot to double quote my variables in my ancient tcsh startup startup scripts using in other systems, but of course I have checked the issue on a clean environment before reporting that. Forget the tcsh, this is coming from the bash as well the very first time you are running Cygwin:

-------------------
Copying skeleton files.
These files are for the users to personalise their cygwin experience.

They will never be overwritten nor automatically updated.

'./.bashrc' -> '/home/kavalpa//.bashrc'
'./.bash_profile' -> '/home/kavalpa//.bash_profile'
'./.inputrc' -> '/home/kavalpa//.inputrc'
'./.profile' -> '/home/kavalpa//.profile'

$ echo $PATH
/usr/local/bin:***/usr/bin***:/cygdrive/c/Program Files/Npm:[snip]:/cygdrive/c/Program Files/PHP/composer/bin:***/usr/bin***:/cygdrive/c/Users/kavalpa/AppData/Local/Microsoft/WindowsApps
-------------------

The issue is enclosed with a three-star notation. I have checked /etc startup files, but I couldn't figure out why this is happening. It is also weird the location at the end before user's personal paths.

There is a point with the DLLs in the path of Windows, but where do you store your wrapper scripts? Because I usually place them in my ~/bin, which is the only solution when you don't have admin rights on your machine. When I do have admin rights, I usually place them in /usr/local/bin.
