DESCRIPTION:
Often Grid Engine end users get job failures when they specify

    # qsub -b y <relative-path>

since then clean job execution depends on PATH environment variable at execution
time. Due to this dependency at execution time these cases are hard to analyze
and sometimes fixing the problem is not possible at all due to the fact that
PATH environment is not set from users $HOME/.profile or $HOME/.login in certain
cases. The cases are when actually no shell was started (e.g. -noshell) or when
the shell does not source $HOME/.profile or $HOME/.login as it does since it
simply does not regard the hyphen ("-") that was specified as arg0 with execv(2).

SUGGESTED FIX:
When "-b y" is used, relative pathes shall generally be rejected, if the
binary/script can not be found already based on the PATH environment at
submission time. If the binary/script can be found Grid Engine shall assume that
the full path as resolved at client side be valid also at the execution host.
