This patch changes pdump_load on Windows so that it finds the .dmp file by changing the ".exe" at the end of the path XEmacs was launched from to ".dmp". Previously it was looking in the current working directory for xemacs.dmp. It doesn't seem like a good idea to depend on the CWD being correct, even if it usually is (it wasn't in my debug setup). If the path is very long or doesn't end in ".exe" it falls back to the previous way of finding the dump file. I imagine a similar hack could be done on Unix, but I'm not familiar enough with the various flavors supported by XEmacs to know the best way to do it.
