<p class="MsoPlainText">When building an RTEMS 5 BSP for LEON3 we get the warnings below regarding missing _Timespec functions. These warnings result in linker errors when building an application that uses a rtems_bsdnet_ifconfig struct supplied as the network
interface member of a rtems_bsdnet_config struct. We believe the fix is to add the following include in greth2.c: #include <rtems/score/timespec.h>. (Note there is also a trivial printf formatting warning that should also be fixed.)<o:p></o:p></p>
