What I was trying to say is, Linux allows execve to return POSIX error
codes which are not covered by the POSIX specs of execve.  EACCES is a
perfectly valid error code here, but we can also use another one for
border cases, like the suggested one.

Please note, I'm neither strongly for nor against changing the error
code in the case discussed in this thread.  But if it can help users
in a border case...
