[omniORB] compiling problem with omnithread

[W T Meyer]

I get the following error messages when I try to compile my 
application using g++ version 3.4.6 under Scientific Linux 4.5.  It 
may well be a problem with the upgrade to SL 4.5, but I can't locate 
the source.  Does anyone have helpful thoughts?  Things to try?

Thanks,

many lines in sched.h and pthread.h ]
