Re: [boost] Re: [iostreams] Compilation errors with MSVC 8

The warning from is_abstract.hpp may be because iostreams includes <boost/type_traits/is_convertible.hpp>. It's not your problem, but could be simply fixed by changing line 81 of is_abstract.hpp from this:

BOOST_STATIC_ASSERT(sizeof(T));

to this:

BOOST_STATIC_ASSERT(sizeof(T) != 0);

I'll get that fixed. Strangely the warning doesn't show up in any of the type_traits tests, and seems to be very specific to certain instantiations <shrug>. John.
