I was being lazy and trying to avoid starting my Linux VM :-)  But I 
just wrote an app like the above, compiled it as "app", moved the 
executable to /dmd/bin, and ran it.  As suspected, argv[0] was "app" and 
not "/dmd/bin/app" as the DMD front-end seems to expect.  I also 
couldn't find a built-in way to determine the location of the executing 
process, so it may be that DMD will have to iterate across the PATH list 
as Build does.
