Type Traits tests are run with warnings-as-errors and GCC 3.x emits warnings with this test that I haven't been able to suppress.

Apparently the compiler can't cope with these - later versions are fine though. Probably work-round-able if someone would care to look into these.

This failure is caused by the lack of compiler support for class template partial specialization. A limited subset of the tested functionality is available on the compiler through a user-side workaround (see http://www.boost.org/libs/type_traits/index.html#transformations for details).

See bug 99776 'enum UIntEnum { value = UINT_MAX } is promoted to int' http://lab.msdn.microsoft.com/ProductFeedback/viewfeedback.aspx?feedbackid=22b0a6b7-120f-4ca0-9136-fa1b25b26efe https://developercommunity.visualstudio.com/content/problem/490264/standard-violation-enum-underlying-type-cannot-rep.html

This functionality is available only on compilers that implement C++ Core Language Defect Report 337.

The Type Traits library is broken when used with Sunpro-5.3 and the argument to the template is an array or function type. Most other argument types do work as expected: in other words the functionality is limited with this compiler, but not so much as to render the library unuseable.

The Type Traits library is broken when used with Sunpro-5.8 and the argument to the template is a function type. Most other argument types do work as expected: in other words the functionality is limited with this compiler, but not so much as to render the library unuseable.

This fails with an internal compiler error, there is no workaround as yet.

Older versions of MWCW incorrectly align pointers to member functions (they use 12-byte boundaries, rather than a power-of-2 boundary), leading to alignment_of / aligned_storage to fail with these types on this compiler.
