This is currently not supported directly.  You can rename the .pdmp
file by hand to have the same base name as the Emacs executable, and
then it should work, provided you also rename the other *.pdmp files
so that none of them is called "emacs.pdmp" literally.  Alternatively,
you can use a shell script or a shell alias with loads a specific
.pdmp file usingh the --dump-file=FILE command-line option.
