        * gimplify.c (gimplify_switch_expr): If case labels cover the whole
        range of the type, but default label is missing, add it with one
        of the existing labels instead of adding a new label for it.

        * gcc.dg/pr39666-1.c: New test.
        * gcc.dg/pr39666-2.c: Likewise.
        * g++.dg/warn/Wuninitialized-4.C: Likewise.
