No.  This was hashed out about a year ago in either c.u.q or c.u.w.
Basically, it boils down to the fact that you have no idea where you
came from, and the closest you could come is to count on the shells to
*mostly* give you the right answer *most* of the time in argv[0].
However, programs that do execv() are free to provide *whatever* they
want.  So, you're out of luck, and subject to spoofing.

Just another UNIX hacker,
