Dunno about ntldd, but if you execute Emacs from Dependency Walker it
will report dlls loaded at runtime.

Yes, if you _execute_ emacs from DependencyWalker and if you request that the dll be loaded.

Until then, you don't know.

I have built a list of dlls that maybe requested by emacs using pacman.

I used pacman to know which package holds some dll like gnutls, and then I listed all

its dependencies, and filtered the dlls in the dependencies.

Unfortunately, knowing the dlls is not enough. For example, gnutls also need to have an accessible

ca-bundle for certificates. ImageMagick needs all its helpers to handle various file formats, etc.
