I've now got native-comp building successfully to a package.

At the moment, the compilation process only runs successfully when run
from an mingw64 shell, so I haven't got the dependencies working
correctly yet.

The error I am getting is this:

Compiling c:/msys64/home/Administrator/emacs-upload/emacs-28.0.50-snapshot-feature_native-comp-windows-2021-02-04/share/emacs/28.0.50/lisp/emacs-lisp/cl-lib.el...
compiling to c:/Users/Administrator/AppData/Roaming/.emacs.d/eln-cache/28.0.50-14889799/cl-lib-8b938900-d1df28b7.eln
x86_64-w64-mingw32-gcc-10.2.0: fatal error: cannot execute 'as': CreateProcess: No such file or directory
compilation terminated.


I've tried putting as.exe manually into the package but that isn't
enough. as.exe doesn't seem to have any dll dependencies itself.

Andrea what other tools does native-comp require to have around? Is
there a good way to debug the compilation process, so I can work out
what the file missing is?
