    c++: Fix diagnostic for binding lvalue reference to volatile rvalue [PR
100635]

    The current diagnostic assumes the reference binding fails because the
    reference is non-const, but it can also fail if the rvalue is volatile.

    Use the current diagnostic for non-const cases, and a modified
    diagnostic otherwise.

    gcc/cp/ChangeLog:

            PR c++/100635
            * call.c (convert_like_internal): Print different diagnostic if
            the lvalue reference is const.

    gcc/testsuite/ChangeLog:

            * g++.dg/conversion/pr100635.C: New test.
