Dirk,
I'll add that to the asyn known problems. Does VS 10 have the same problem with the header file as VS Express 2008 that Anthony Owen discovered?

Compiling asyn with make USR_CFLAGS=/D_WIN32_WINNT=0x0500 solves the
problem. I have no idea why _WIN32_WINNT is set to something >= 0x0600
(=Vista).
