Óscar Fuentes said there were no changes in the layout lately, I assume
we just installed MSYS/MinGW differently as Phil did.  (I'm going to
learn what is recommended as the default path for MSYS/MinGW in
INSTALL.W64)

Thanks, I had a look.  Before I forget - just in case - only stuff in
"with-native-compilation" is updated!  But I guess you'll upload only
"with-native-compilation" anyway. :-)

Please see in the attached file a comparison of Arash Esbati's (thanks
again), mine and your list of DLLs.  And it looks reasonable to me. 

I'm afraid we can't compare 27.2 builds from Phil's setup one on 1 with
our 28 builds.

Very good, thank you kiddos! :-)

As far as I understood, this is exactly what Eli hoped for.

Such systems can't natively compile stuff but benefit from available
.eln files. :-)

Please push.

Except others, with more experience, want to chime in..

They are looking good

(.. I don't comprehend the -static issue, yet.  But don't mind.)
