#1978 new defect

sem_open lacks support of "mode" argument

Description (last modified by Sebastian Huber)

sem_open in cpukit/posix/src/semopen.c lacks support of sem_opens's "mode"
argument:

sem_t *sem_open(const char *name, int oflag);
sem_t *sem_open(const char *name, int oflag,

mode_t mode, unsigned int value);

The RTEMS implementation only pretends to be supporting it,
which also reflects in a GCC warning:
cpukit/posix/src/semopen.c:51:30: warning: variable 'mode' set but not used
