No, you misunderstood. I _did_ build with consistent wchar_t option (off
in that case). But boost won't build the date time library without
native wchar_t. I tried with and without stdcxx library on windows with
vc7.1, it never worked. I needed to turn wchar_t on for it to work (with
<native-wchar_t> or so....), there seems to be kind of a boost bug ;o)
but i'm not sure about that.
On vs8 this is not a problem, since wchar_t is native by default. On
vc7.1 i don't want to rebuild everything, better: i don't want to change
our build mechanisms, since those are many, and not too easy to change
;o)

Cheers, Markus

Oh right, if you build the std lib without /Zc:wchar_t and build boost
with it, then that absolutely will lead to linker errors at the very
least.  Try building with consistent /Zc:wchar_t options and that should
fix things (hopefully!).
