Jeff,
I can answer some of these...
I've been playing with date_time to try and get it to do the right thing with VC++ when /Zc:wchar_t is *not* specified, and I've come up with a list of questions for you if you don't mind :-)
1) What's the meaning of USE_DATE_TIME_PRE_1_33_FACET_IO? Without it the testtime_wstream.cpp test case fails even with /Zc:wchar_t, this is a source of confusion if you're building the building the tests in your IDE for whatever reason.
2) Without USE_DATE_TIME_PRE_1_33_FACET_IO the testgrep_wstream.cpp test doesn't compile irrespective of the /Zc:wchar_t option:
With boost 1.33, date_time uses a totaly new system for streaming IO. We kept the pre 1.33 streaming code, and tests, in the library. That macro allows a person to choose which system they want to use. This is all in the documentation: http://tinyurl.com/cyu2d The old tests are dependant on the old code, therefore, they fail to compile when the macro is not defined. ...snip...
3) Finally there are a lot of places where an unsigned short is written to or read from a stream: unfortunately the dinkumware lib treats these "as if" they were a wide character value, rather than an integer. Casting to unsigned int in these cases would fix that, but it's a horrid cludge, and I don't know what you might think about that!
I'll let Jeff handle this one... Bart
