I'd say refactor the code ... either at the uses or by turning the
macros into inline functions (I know that's what other people think
should happen to all macros in GCC). Refactoring the uses may
end up in uglier code like
|| (tem = gimple_assign_rhs_code (def_stmt),
!CONVERT_EXPR_CODE_P (tem))
(there was even a way to have tem declared at that point in C++...)
