[Bug c++/43909] New: trunk rev158780. compile with --enable-build-with-cxx fails in get_function_part_constraint

../../g++-4.5.svn/gcc/tree-ssa-structalias.c: In function 'constraint_expr
get_function_part_constraint(variable_info*, unsigned int)':
../../g++-4.5.svn/gcc/tree-ssa-structalias.c:3644:29: error: enumeral and
non-enumeral type in conditional expression [-Werror]
cc1plus: all warnings being treated as errors

tree-ssa-structalias.c:3644: c.var = ai ? ai->id : anything_id; 
                            this is a enum constant ^^^^^^^^^^^
causing a c++ warning that is being treated as fatal.

Maybe add an explicit cast to unsigned int?
