The canonical test is to say

  C:\sys\emacs.28\bin>set EMACSLOADPATH

That should produce an explicit "not defined" response if the variable
is not defined.

Start regedit and search for the variable's name with C-f followed by

That last list element is the problem.  I don't know how it gets
there, ideas are welcome.

Phillip, perhaps try stepping with GDB through init_lread and its
subroutines, and see where does this come from.  I expect that to be
the value of PATH_DUMPLOADSEARCH, but it shouldn't be used in a normal
startup of an installed Emacs.  I guess I'm missing something here.
Maybe it's somehow related to the fact that there's no --prefix at
configure time, but I'm not sure.
