2009-04-08linux-user: fix problems with inotify syscallsaurel32
The sys_inotify* calls are defined if the target supports them and the host supports the necessary syscalls. But the syscalls are handled if the target supports them. This situation leads to compilation failures when the host doesn't support the necessary syscalls, as the linker will complain about undefined functions. Fix this state of affairs by making the handling conditions the same as the call definition conditions.

2008-11-14target-alpha: implement getxuid and getxgid syscallsaurel32
This patch implemented the setxuid and setxgid syscalls for Alpha. These syscalls return two values, both uid/euid and gid/egid. In addition to returning the first value in $v0, the additional value is returned in the $a4 register. The syscalls are used instead of the separate syscalls for those values used on other architectures (this is probably because Alpha Linux started out syscall compatible with DEC/OSF/Tru64). With this patch, the perlbmk benchmarks from Spec2000 run properly. (Vince Weaver) git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5722 c046a42c-6fe2-441c-8c8c-71466251a162
