I understand, thanks. I'll grab all DLL filenames of the
Windows/system32 folder and filter them out. Or how would you build or
hard-code such a filter list?

Would it make sense to you to have the (additonal) capability for
copy-file to do nothing if the target file already exists?
At the moment I can 1) trigger an error, 2) overwrite an existing file
and 3) ask for confirmation either to overwrite or to have an error. So
3) is actually only an - annoying - way to have 1) or 2), there's no way
to leave an existing file alone without an error.
And here's another thing I stumbled over: An excerpt of copy-file's
documentation string:
OK-IF-ALREADY-EXISTS is an integer, request confirmation from the user
about overwriting; this is what happens in interactive use with M-x.
The interactive part in the documentation is unnecessary, I think, the
request happens for me in batch mode as well.

Actually my code was copying all of above tiff DLLs to the bin
folder.

I see, I'll just copy the available, leftmost DLLs.

Please tell me where I can find above definition of
dynamic-library-alist? Mine (Emacs-27.2) just says:
dynamic-library-alist is a variable defined in ‘C source code’.
((harfbuzz "libharfbuzz-0.dll")
(gdiplus "gdiplus.dll")
(shlwapi "shlwapi.dll")
(xpm "libxpm.dll" "xpm4.dll" "libXpm-nox4.dll")
(png "libpng16.dll" "libpng16-16.dll")
(tiff "libtiff-5.dll" "libtiff3.dll" "libtiff.dll")
(jpeg "libjpeg-8.dll")
(gif "libgif-7.dll")
(svg "librsvg-2-2.dll")
(webp "libwebp-7.dll" "libwebp.dll")
(sqlite3 "libsqlite3-0.dll")
(gdk-pixbuf "libgdk_pixbuf-2.0-0.dll")
(glib "libglib-2.0-0.dll")
(gio "libgio-2.0-0.dll")
(gobject "libgobject-2.0-0.dll")
(gnutls "libgnutls-30.dll")
(libxml2 "libxml2-2.dll" "libxml2.dll")
(zlib "zlib1.dll" "libz-1.dll")
(lcms2 "liblcms2-2.dll")
(json "libjansson-4.dll")
(gccjit "libgccjit-0.dll"))

I'm struggling to understand that, I thought ./configure would sort out
what is necessary and available on my system?
Thank you for your interest
