Hi,

I just tried to get the simulator from trunk built but failed here:

In file included from ../../../../xenomai/sim/../include/posix/posix.h:29,
                 from
../../../../xenomai/sim/../ksrc/skins/posix/internal.h:24,
                 from
../../../../xenomai/sim/../ksrc/skins/posix/thread.h:23,
                 from
../../../../xenomai/sim/../ksrc/skins/posix/sched.c:48:
../../../../xenomai/sim/../include/posix/pthread.h:246: conflicting
types for `pthread_attr_getaffinity_np'
/usr/include/pthread.h:383: previous declaration of
`pthread_attr_getaffinity_np'
../../../../xenomai/sim/../include/posix/pthread.h:249: conflicting
types for `pthread_attr_setaffinity_np'
/usr/include/pthread.h:377: previous declaration of
`pthread_attr_setaffinity_np'

Looks like glibc-2.4 (that one comes with my opensuse 10.1) now also
knows get/setaffinity. Prototypes of glibc:

extern int pthread_attr_setaffinity_np (pthread_attr_t *__attr,
                                        size_t __cpusetsize,
                                        __const cpu_set_t *__cpuset)
__THROW;
extern int pthread_attr_getaffinity_np (__const pthread_attr_t *__attr,
                                        size_t __cpusetsize,
                                        cpu_set_t *__cpuset) __THROW;

Moreover, I get tons of this warning:

/usr/include/bits/pthreadtypes.h:69: warning: unnamed struct/union that
defines no instances

But this is an "imported" issue, isn't it? Likely due to some picky gcc
switch during the simulator build.

PS: I already committed this tiny fix to make gcc-4.1 happy:
