I don't have the exact failure message around anymore, but i will try
again in some time. The error was, that somehow an operator<< was not
found. Funny about that was, that it was the basic_ostream<wchar_t,
...>::operator<<(basic_ostream<wchar_t,...>, const std::string&) as far
as i remember. I had a look at the preprocessor output, but didn't see
anything suspicious there. (replace wchar_t with unsigned short in the
case of /Zc:wchar_t- (off), which *was* the case).
I also asked other colleges from my company (some c++ freaks ;o)), but
they couldn't find anything either. Very weird.
The very same thing happened when using the complete normal windows
build with vc7.1 when using <native-wchar_t>off. Maybe someone can try
this, to see if it has something to do with my machine (??). So i think
this should be reproduceable even without stdcxx, and the normal windows
STL implementation. My bjam flags where:

bjam_flags="<runtime-link>dynamic"
bjam_flags="${bjam_flags} <threading>multi"
bjam_flags="${bjam_flags} <native-wchar_t>off"

Cheers, Markus

Well, that's fairly hard for me to imagine based on what is in the lib.
The tests are a different story...many platforms have issues with
correct support for wchar and hence fail a variety of date-time tests
designed to exercise wchar support.  Perhaps you need to post the
failure details....or did I just miss them? The other thing I'll mention
is that the platforms that use the Rogue Wave library, in general,
haven't been the best for Boost support in general.  So I wouldn't be
surprised at all if there are plenty of boost compatibility issues with
apache stdcxx.  As an example, in date-time I had to add some code for
facets that returned id's to make things work with the RW
library:

//time_facet.hpp
#if defined (__SUNPRO_CC) && defined (_RWSTD_VER)
       std::locale::id& __get_id (void) const { return id; } #endif

I don't know if this is still needed, but if it is you won't be getting
it because the config macros won't select it.  If you search the boost
source on RWSTD you'll find other workarounds.
