No.  argv[0] is *always* set from the program name in MS-DOS,
regardless of what you pass for exec*.  DJGPP bypasses MS-DOS in order
to provide this functionality, so if you were using a djgpp program to
call another djgpp program (via exec*), the argv array is passed
intact.  Note, however, that it's much more efficient to use the
symbolic link mechanism that djgpp provides instead.
