Then the compiler (or linker) will almost certainly optimize it away
(i.e. with patch #2 configure would fail at least with some compilers.
And yes, that return was added by me for exactly that reason, originally
it was just return 0 and I did try ascii_name[0] first and it did not help).

If it works on bigendian and Diego is ok with it.
