+ * stdlib/errno.h: Remove __need_Emath and __need_error_t logic.
+ Reorganize file. Declare errno here. When __ASSEMBLER__ is
+ defined, don't declare anything other than the E-constants.
+
+ * include/errno.h: Change conditional for exposing internal
+ declarations to (not _ISOMAC and not __ASSEMBLER__).

+ * sysdeps/unix/sysv/linux/mips/bits/errno.h
+ * sysdeps/unix/sysv/linux/sparc/bits/errno.h:
+ Add multiple-include guard and check against improper inclusion.
+ Remove __need_Emath logic. Don't declare errno here. Ensure all
+ constants are defined as simple integer literals. Consistent
+ formatting.
+ * sysdeps/mach/hurd/errnos.awk: Likewise. Only define error_t and
+ enum __error_t_codes if __ASSEMBLER__ is not defined.
+ * sysdeps/mach/hurd/bits/errno.h: Regenerate.
+
+ * argp/argp.h, string/argz.h: Don't define __need_error_t before

+ Also, the error constants should, if at all possible, expand to
