commit 6f47864214658e3bb31776eded6dfd44c3237bb6

    Fix newlib/testsuite/newlib.search/hsearchtest.c compilation for 16-bit targets.
    
    When the test case is compiled for a 16-bit target, the compiler emits
    the two warnings shown below, causing the test to fail. The code assumes
    that pointers are 32 bits wide, which obviously is not true. This patch
    fixes the issue.
