[Gmsh] Using the Python API under Win 10 + Msys2

[Santiago Serebrinsky]

I guessed so, given that I got

  gmsh-git-Windows64-sdk.zip

and gmsh-4.0.dll is inside it.
Having Win 10, I need a 64-bit version.
Now, checking gmsh-4.0.dll, I used a couple of alternative methods:

1. As per https://stackoverflow.com/a/495365/2707864 I used

  $ file gmsh-4.0.dll
  gmsh-4.0.dll: PE32+ executable (DLL) (GUI) x86-64 (stripped to external
PDB), for MS Windows

I guess PE32+ corresponds to 64 bit.

2. I used https://github.com/lucasg/Dependencies v1.8

It seems to indicate that gmsh-4.0.dll depends on many 32 bit dlls, so I
wouldn't be sure.
