This does't work in my case, because at that point, "${srcdir}"
contains the relative path "../emacs.git", not something like
"/c/whatever" or "c:/whatever".

I think that the right fix is to replace *all* the treatment of
patterns like the above ("/c/whatever" or "c:/whatever") with logic
based on the "pwd -W" feature of MSYS.

IOW, an MSYS path doesn't have to match none of the above patterns, so
the only reliable way of getting a Windows-native path is with "pwd
-W".

Therefore, things line "msys_to_w32", "msys_lisppath_to_w32" should be
replaced with the above criteria.
