11683	Boost thread 1.59 problems on WinXP SP2	Daniel	viboes	"Hi,
when I compile my software using Boost thread 1.59.0 and run it on a WinXP SP2 machine it won't start. 
DependencyWalker shows the missing GetLogicalProcessorInformation() as mentioned in ticket:10824.

I think the fix from ticket10824 has been overwritten by later commits.
From the history for thread/src/win32/thread.cpp:

1) initial PR on this matter from viboes: physical_concurrency() to ""return 0"" in case of WinXP [1]

2) fix for VS2010 compiler [2]

3) revert 1) by Niall: ""return hardware_concurrency()"" again [3]

The ticket:10788 proposed another solution. 
Could I ask you to look into this matter again please?

Thanks,
Daniel
