Added #include "os_include/sys/os_time.h" and

data member itimerval itimer_ wrapped with ACE_USES_GPROF.
This data member will hold the thread profiling timer.
Added Accessor function to itimer_ data member.
(ACE_Base_Thread_Adapter) Constructor calls getitimer.
(ace_thread_adapter) Calls setitimer.
Both are wrapped with ACE_USES_GPROF
