That's the point -- the modifications were first checking
whether the file named in `argv[0]' exists; if I type `foo' then
this will check for `foo' in the current directory, when the
program which was run would be in some other directory.  On
finding `foo', it wouldn't bother checking the /proc entry or
looking elsewhere in the path.  That's why I suggested checking
for slashes instead, then doing a path search; or, on Linux,
*always* doing the /proc test, and falling back to the other
methods only if that fails.
