I'm not configure maintainer and I'm not even quite good in shell scripts.
However, I think there are few things that may be improved.
1. Don't try to compile array[-1], with gcc you never know, it may
actually compile it.
Better try to use #if #error directives.
2. No need to check for 0 case. What are we going to do if it succeeds?
3. I think that MP_WORDSIZE <bits> , your code returns it as <chars//bytes//>
