OK. It's good to see that the sum is mentioned
somewhere.

Very good.

I agree.

This is where I must disagree.
The error message complains about "arguments", but
the problem is with the "environment". It
inevitably misleads users, especially new users.
It seems to me that
1.) execve() should return a more precise
error message that mentions the "environment",
and
2.) "Additional error numbers may be defined
on conforming systems; see the System
Interfaces volume of IEEE Std 1003.1-2001."

Having said that, thank you for your time and
attention.
All the best,
Kingsley
