    c++: unsigned int32_t enum promotion [PR102804]

    There's been an extension for a long time to allow applying 'unsigned' to
an
    int typedef, but that was confusing the integer promotion code.  Fixed by
    forgetting about the typedef in that case.

    I'm going to make this an unconditional pedwarn in stage 1.

            * decl.cc (grokdeclarator): Drop typedef used with 'unsigned'.

            * g++.dg/ext/unsigned-typedef1.C: New test.
