MSYS2 cannot put anything anywhere, it can only map some /foo
directories to certain Windows directories.  But those MSYS2 mappings
do not and cannot change the places where the compiler looks for its
headers.

The user who installs XPM is the one who decides where its headers
will be.  MSYS2 cannot possibly change that.
