Hi Joe!

When I'm running from cmd.exe either or from Emacs, in both cases there is  
line 

| info: prepending to PATH: C:\pdfsizeopt\pdfsizeopt_win32exec

There is another GS, it resides in the msys64 system. I added the /bin path to 
the PATH and tried again, no success.

And furthermore: if pdfsizeopt is called by Emacs, python is being found:

| Traceback (most recent call last):
|    File "C:\pdfsizeopt\pdfsizeopt_win32exec\python26.zip\runpy.py", line
|    122,

And if pdfsizeopt finds python, why not gswin32c.exe? 

Next idea: what if I rename the gs-exes of msys64? Maybe Emacs, depending on 
mingw64, asks the mings64 Ghostscript installation? So I renamed the gs-exes 
there, but no success. 

What does Emacs do differently from cmd.exe?
