    [PATCH] PR modula2/115003 exporting a symbol to outer scope with a name
clash causes ICE

    An ICE will occur if an unknown symbol is exported and causes a name
    clash.  The error mechanism attempts to find the scope of an unknown
    symbol.  This patch adds a missing case clause to GetScope and returns
    NulSym if the scope is an unknown symbol.

            * gm2-compiler/SymbolTable.mod (GetScope): Add UndefinedSym
            case clause and return NulSym.
