[boost] [asio and thread] don't play well together under cygwin?

Greetings,

I have a header file that includes both <boost/thread> and <boost/asio>, 
which results in the compilation errors below under cygwin.  If I take 
out <boost/thread> then things are fine, except that I need it for my 
application :)  I have "-D__USE_W32_SOCKETS -D_WIN32_WINNT=0x0501" in my 
compile flags, per the asio documentation.  Taking them out appears to 
resolve the errors below, but causes other errors for asio.

Has anyone else run into this problem and found a solution?

-Brian
