Hi, I have x-compiled Boost using Pthreads-w32, using threading=multi,single threadapi=pthread. But when I x-compile my application Boost uses the win32 headers. I have looked at the thread sources but I cannot find out if it just should work or that I should use some macros. Can anyone help me with this? TIA -- Groeten, Joost Kraaijeveld Askesis B.V.
