             Bug #: 55269
           Summary: Rename tree_node complex field to avoid conflict with
                    C99 complex type
    Classification: Unclassified
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: treelang
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: peter@colberg.org


Dear GCC developers,

The identifier of the union field "tree_complex complex" of union tree_node in
tree.h potentially conflicts with the macro "#define complex _Complex" defined
in C99 <complex.h>.

I stumbled over this issue while writing a plugin for GCC using the foreign
function interface of LuaJIT. LuaJIT predefines C99 complex types, both
"_Complex" and "complex". Therefore LuaJIT rejects "tree_complex complex"
of tree_node as a declaration with an invalid declaration.

Could the tree_complex field be renamed, e.g., to "complex_cst"?

(The suggestion stems from the name of the macro COMPLEX_CST_CHECK.)

Regards,
Peter
