+ * sysdeps/sparc/sparc32/dl-machine.h
+ (elf_machine_fixup_plt): During rtld bootstrap, always perform
+ flushes as the kernel will emulate it when the underlying cpu does
+ not implement flush.
+
+ * sysdeps/unix/sysv/linux/sparc/sys/kernel_termios.h: Move...
+ * sysdeps/unix/sysv/linux/sparc/kernel_termios.h: ...to here.
+
+ * sysdeps/unix/sysv/linux/sparc/sparc32/__sigtrampoline.S: Remove.
+ * sysdeps/unix/sysv/linux/sparc/sparc32/Makefile: No longer build
+ trampoline code.
+
+ * sysdeps/unix/sysv/linux/sparc/sparc32/clone.S
+ (__clone): Branch to label .Lerror not __clone_syscall_error.
+ (.Lerror): Fixup EINVAL setting.
+ * sysdeps/unix/sysv/linux/sparc/sparc32/getgroups.c: New file.
+ * sysdeps/unix/sysv/linux/sparc/sparc32/setgroups.c: New file.
+ * sysdeps/unix/sysv/linux/sparc/sparc32/syscalls.list
+ (__syscall_getgroups, __syscall_setgroups): Add.
+
+ * sysdeps/unix/sysv/linux/sparc/sparc32/sigaction.c
+ (__sigaction): Member name is k_sa_handler. Use memcpy to copy
+ around sa_mask data.

+ * math/math.h: Include bits/nan.h when compiling for ISO C 9x.
+
* string/Makefile: Make sure test-ffs does not use builtins.

*highly* recommended *not* to use --enable-static-nss since this makes
the behaviour of the programs on the system inconsistent.
+?? I just upgraded my Linux system to glibc and now I get
+ errors whenever I try to link any program.
+
+{ZW} This happens when you have installed glibc as the primary C library but
+have stray symbolic links pointing at your old C library. If the first
+`libc.so' the linker finds is libc 5, it will use that. Your program
+expects to be linked with glibc, so the link fails.
+
+The most common case is that glibc put its `libc.so' in /usr/lib, but there
+was a `libc.so' from libc 5 in /lib, which gets searched first. To fix the
+problem, just delete /lib/libc.so. You may also need to delete other
+symbolic links in /lib, such as /lib/libm.so if it points to libm.so.5.
+
? Source and binary incompatibilities, and what to do about them
?? I expect GNU libc to be 100% source code compatible with
