Ah, OK.  I guess MSYS modified your c:/usr/share/info into
/usr/share/info because your Texinfo is an MSYS package.

That depends, see above.  In general, MSYS is supposed to support
both styles alike; anything else is a bug in MSYS.

Looks like the lines in info/dir which came from the original file in
the source tree (which has Unix-style EOLs) are copied verbatim, while
other lines have DOS EOLs.

Does the same happen if you invoke install-info manually?

I think the cause of this is that MSYS programs use binary I/O mode,
so they output the lines with whatever EOL format they happened to
have in their source files.

(Using the native port of makeinfo, I don't have this problem.)
