Yes.
GCC 4.3 doesn't define the injected-class-name for the base, so this
patch is needed:
--- a/gcc/opt-problem.h
+++ b/gcc/opt-problem.h
@@ -214,7 +214,7 @@ class opt_result : public opt_wrapper <bool>
/* Private ctor. Instances should be created by the success and failure
static member functions. */
opt_result (wrapped_t result, opt_problem *problem)
- : opt_wrapper (result, problem)
+ : opt_wrapper<bool> (result, problem)
{}
};
