    This patch removes the use of the "register" keyword from the bsearch() and bsearch_r() functions supplied by libiberty.  The register keyword is deprecated in C++17.

    include/
            * libiberty.h (bsearch_r): Remove use of the register keyword from
            the prototype.
    
    libiberty/
            * bsearch.c (bsearch): Remove use of register keyword.
            * bsearch_r.c (bsearch_r): Likewise.
