Hi,

I am using _QNX_SOURCE compilation flag to compile my application to avoid 
"#error POSIX Scheduling needs P1003.1b-1993 or later" error,

My application compilation is success... but I am worried about any other run time errors because of this compilation 
flag.

I am testing only very minor things , so as off now now issues. 

Let me know if there is any alternative to avoid above mensioned error.


Regards,
Vinod.
