GCC treats the pragma as a statement, so that the else branch only
consists of the pragma, not the return statement.

Fixes commit a725ff1de965f4cc4f36a7e8ae795d40ca0350d7 ("Suppress
-Wcast-qual warnings in bsearch").

---
v2: Added bug number.  Tested on i686-linux-gnu and x86_64-linux-gnu.
    The regressions are gone.
