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41 | // For GCC, 4.4 and earlier are no longer maintained so there is no need | |
