Including thread.hpp in a project using the /clr compiler flag results in
the following output.
{{{

I couldn't find any tickets on this problem however a quick google brought
up someone who has encountered this before:
http://groups.google.com/group/boost-
list/browse_thread/thread/9662c882efc153b6?pli=1
unsigned should probably convert to ptrdiff_t implicitly but it's throwing
a wobbly with /clr. Maybe this is fair enough as specifying /clr opens a
whole new world of pain (I was just trying my luck really!), nevertheless
would it be sensible to change the types from unsigned to ptrdiff_t as
that's what operator[] requires?
