Yes, the

typedef struct Scheduler_Context Scheduler_Context;

only creates the typedef and the structure name. This is why I also wrote:

Then you have to make sure that #if !defined(RTEMS_SMP) no objects of 
this type are used.

For example:

diff --git a/cpukit/include/rtems/score/schedulersimple.h 
b/cpukit/include/rtems/score/schedulersimple.h
index d9acd3dea0..0db72b2a51 100644
--- a/cpukit/include/rtems/score/schedulersimple.h
+++ b/cpukit/include/rtems/score/schedulersimple.h

   * @brief Simple scheduler context.
   */
  typedef struct {
+#if !defined(RTEMS_SMP)
    /**
     * @brief Basic scheduler context.
     */
    Scheduler_Context Base;
+#endif
