The compile time failure has been fixed, but there's a runtime failure now. 
It apears there's a disagreement between WCHAR_MAX and 
numeric_limits<wchar_t>::max():

WCHAR_MAX                       0x7fffffff
numeric_limits<wchar_t>::max(): 0xffffffff

At least that appears to be the case from what I can deduce, can you double 
check?

I'm not sure that's fixable by us: if this is the case then it looks more 
like a QNX or possibly libstdc++3 bug to me.  Interestingly, config_info 
reports wchar_t as unsigned so the value for WCHAR_MAX does look wrong to 
me.

Oh I don't know, looking again at integer_traits we could fix the test case 
by forcing the ::const_max member to have the same value as 
numeric_limits<>::max(), but then both would disagree with WCHAR_MAX !  So 
<shrug> basically, I don't know what the right thing to do is here.
