rtems-libbsd Build Error

[Joel Sherrill]

Hi

I am trying to build rtems-libbsd for xilinx_zynq_a9_qemu using
tools and RTEMS built from their master branches. Both the
master and 5-freebsd-12 branch fail to build with this error:

In file included from ../../rtemsbsd/rtems/rtems-kernel-thread.c:56:0:
/home/joel/rtems-class/tools/5/bsp-install/arm-rtems5/xilinx_zynq_a9_qemu/lib/include/rtems/score/objectimpl.h:
In function '_Objects_Free':
/home/joel/rtems-class/tools/5/bsp-install/arm-rtems5/xilinx_zynq_a9_qemu/lib/include/rtems/score/objectimpl.h:937:17:
error: 'Objects_Information {aka struct Objects_Information}' has no member
named '_bsd_free'
   ( *information->free )( information, the_object );

I think the solution is that the structure member free needs to be renamed.

61357479 (Sebastian Huber 2019-12-16 14:50:59 +0100 213)   void ( *free )(
Objects_Information *, Objects_Control * );

FWIW I was looking at the MISRA C/C++ rules earlier this week and this is a
violation of one of them. You should not have variables, methods, structure
members, etc that use the same name as standard library entiries.
