commit 80a009119ba2330768120476aaad63767b81d543
Author: Jonathan Wakely <jwakely@redhat.com>

Suppress -Wcast-qual warnings in bsearch
The first cast to (void *) is redundant but should be (const void *)
anyway, because that's the type of the lvalue being assigned to.
The second cast is necessary and intentionally not const-correct, so
tell the compiler not to warn about it.
