// MSVC and GCC <= 4.4 have a bug that affects partial specializations of
// nested templates under some circumstances. This affects the implementation
// of SHARK_FUSION_DEFINE_STRUCT_INLINE, which uses such specializations for
// the iterator class's 'deref' and 'value_of' metafunctions. On these compilers
// an alternate implementation for these metafunctions is used that does not 
// require such specializations. The alternate implementation takes longer
// to compile so its use is restricted to the offending compilers.
// For MSVC, the bug was was reported at https://connect.microsoft.com/VisualStudio/feedback/details/757891/c-compiler-error-involving-partial-specializations-of-nested-templates
// For GCC, 4.4 and earlier are no longer maintained so there is no need
// to report a bug.
