Issue with RTEMS 4.12 compiler include path

Gedare,
The command line make uses when attempting to compile my super-simple
test application is:
/opt/rtems-4.12/bin/sparc-rtems4.12-gcc -O0 -g -D__rtems__ -m32 -W -Wall
-Wextra -std=gnu99 -fmessage-length=0
-isystem/opt/rtems-4.12/lib/gcc/sparc-rtems4.12/6.1.1/include
-isystem/opt/rtems-4.12/lib/gcc/sparc-rtems4.12/6.1.1/include-fixed
-isystem/opt/rtems-4.12/lib/gcc/sparc-rtems4.12/6.1.1/../../../../sparc-rtems4.12/include
./tests/spw-test.c -o bin/spw-test -lm
All of the system includes that my version of gcc does define are
included in the command line not because they are needed for building,
but so that codesonar and the clang static analyzer can easily hook into
the build process and be able to find all the system definitions for
proper analysis.
And this is my application:
#include <rtems.h>
#include <bsp.h>
#define CONFIGURE_INIT
rtems_task Init(rtems_task_argument ignored);
#define CONFIGURE_APPLICATION_NEEDS_CONSOLE_DRIVER
#define CONFIGURE_APPLICATION_NEEDS_CLOCK_DRIVER
#define CONFIGURE_APPLICATION_NEEDS_NULL_DRIVER 1
#define CONFIGURE_INIT_TASK_ATTRIBUTES RTEMS_FLOATING_POINT
#define CONFIGURE_INIT_TASK_STACK_SIZE (10 *
RTEMS_MINIMUM_STACK_SIZE)
#define CONFIGURE_MAXIMUM_TASKS 13
#define CONFIGURE_RTEMS_INIT_TASKS_TABLE
#define CONFIGURE_MAXIMUM_DRIVERS 16
#define CONFIGURE_LIBIO_MAXIMUM_FILE_DESCRIPTORS 32
#define CONFIGURE_EXTRA_TASK_STACKS (10 *
RTEMS_MINIMUM_STACK_SIZE)
#define CONFIGURE_MAXIMUM_POSIX_MUTEXES rtems_resource_unlimited(10)
#define CONFIGURE_MAXIMUM_POSIX_CONDITION_VARIABLES
rtems_resource_unlimited(10)
#define CONFIGURE_MAXIMUM_POSIX_SEMAPHORES rtems_resource_unlimited(10)
#define CONFIGURE_UNIFIED_WORK_AREAS
#include <rtems/confdefs.h>
rtems_task Init(
rtems_task_argument __unused ignored)
{
} /* Init() */
This results in the following error:
fatal error: rtems.h: No such file or directory
However, if I add -I/opt/rtems-4.12/sparc-rtems4.12/leon3/lib/include to
the command line (the location of rtems.h), then everything works fine.
My understanding is that this is a "system" include directory that
should be one of the default paths searched by the compiler.
Thanks for your help!
