             Bug #: 2182
           Summary: broken RTEMS CLOCKS_PER_SEC interface, when including
                    only time.h
    Classification: Unclassified
           Product: RTEMS
           Version: 4.10
          Platform: All
        OS/Version: RTEMS
            Status: NEW
          Severity: normal
          Priority: P3
         Component: libcpu
        AssignedTo: joel.sherrill at oarcorp.com
        ReportedBy: johill at lanl.gov


I had to patch Lua (a very portable code) as follows for RTEMS 4.10. I had a
look around in the source and maybe its not possible for _SC_CLK_TCK to be
properly defined when expecting to include only the standard C lib clock
interface via time.h. Maybe its fixed in 4.11, but nevertheless I should
probably file a bug report while I see the issue, in case it isn’t.

/*

#ifdef __rtems__
#  include <sys/unistd.h> 
#endif
