* binutils-all/readelf.exp (prune_read_warnings): Rename to
prune_readelf_wi_warnings.
(readelf_wi_test): New proc: Test 'readelf -wi' by grepping
through its output.
Replace invocation of "readelf_test -wi" with "readelf_wi_test"
* binutils-all/readelf.wi: Delete.

* readelf.exp (proc prune_readelf_warnings): New function.
* binutils-all/readelf.exp (proc prune_readelf_warnings): New
function.
(proc readelf_test): Prune warning messages.
(readelf_test -wi): Add more expected failures.
* readelf.wi: Severly reduce expected output.
* testprog.c (string): Explicitly use unsigned chars.
* binutils-all/readelf.wi: Severly reduce expected output.
* binutils-all/testprog.c (string): Explicitly use unsigned
chars.
(stdio.h, string.h): Remove inclusion.
