This fixes these GCC warnings when -Wsystem-headers is used:

/usr/include/bits/stdlib-bsearch.h: In function ‘bsearch’:
/usr/include/bits/stdlib-bsearch.h:32:13: warning: cast discards ‘const’ qualifier from pointer target type [-Wcast-qual]
    32 |       __p = (void *) (((const char *) __base) + (__idx * __size));
       |             ^
/usr/include/bits/stdlib-bsearch.h:39:16: warning: cast discards ‘const’ qualifier from pointer target type [-Wcast-qual]
    39 |         return (void *) __p;
       |                ^

OK to push?
