Update.
* sysdeps/unix/sysv/linux/seteuid.c (seteuid): Use setresuid32 syscall directly if possible. If __ASSUME_SETRESUID_SYSCALL is defined drop compatibility code. * sysdeps/unix/sysv/linux/setegid.c (setegid): Use setresgid32 syscall directly if possible. If __ASSUME_SETRESUID_SYSCALL is defined drop compatibility code. * sysdeps/unix/sysv/linux/i386/seteuid.c (seteuid): Use setresuid32 syscall directly if possible. * sysdeps/unix/sysv/linux/i386/setegid.c (setegid): Use setresgid32 syscall directly if possible.
