[ECOS] Fw: [ECOS] select err in ecos application

["wangwei" <wangw@start.com.cn>]

and I had notice the changelog of kernel in cvs:

        * src/common/thread.cxx (Cyg_Thread::Cyg_Thread): Initialize
         wakeup_count

Does this change has some relative with this problem?

Best regard

                                           wangwei
