Hi, 2.4.1-pre10 is not compiling (at least) on alpha due to conflicting declarations of sys_wait4() at various locations, e.g. include/asm/unistd.h:575: extern long sys_wait4(int, int *, int, struct rusage *); include/linux/sched.h:566: asmlinkage long sys_wait4(pid_t pid,unsigned int * stat_addr, int options, struct rusage * ru); As far as I can say, the first declaration seems to be correct (confirmation wanted). If so, at least the following files need to be fixed: kernel/exit.c include/linux/sched.h arch/sparc/kernel/signal.c arch/sparc/kernel/sys_sunos.c arch/mips/kernel/signal.c arch/mips/kernel/irixsig.c arch/ppc/kernel/signal.c arch/m68k/kernel/signal.c arch/sparc64/kernel/signal32.c arch/sparc64/kernel/sys_sparc32.c arch/sparc64/kernel/signal.c arch/sparc64/solaris/signal.c arch/sparc64/solaris/signal.c arch/sparc64/solaris/signal.c arch/sparc64/solaris/signal.c arch/arm/kernel/signal.c arch/sh/kernel/signal.c arch/ia64/ia32/sys_ia32.c arch/mips64/kernel/linux32.c arch/mips64/kernel/signal.c arch/mips64/kernel/signal32.c arch/s390/kernel/signal.c Martin - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
