* Makerules (lib%.so: lib%_pic.a): Pass -soname switch giving the library's name including $(libprefix) and major version number. * locale/locale-ctype.c (allocate_arrays): Use xmalloc and bzero in place of xcalloc. * Makeconfig (prefix, exec_prefix, libprefix): Instead of `ifndef', use the $(origin) function to only set these if they are undefined, and not if they are defined to empty. * gnu-versions.h: New file. * features.h (__GNU_LIBRARY__): Increase value to 5.

+/* This file exists to define these few macros. Each specifies a version
+ number associated with the library interface of a piece of the C library
+ which is also distributed with other GNU packages. These pieces are
+ both part of the GNU C library and also distributed with other GNU
+ packages so those packages may use their facilities on systems lacking
+ the GNU C library. The source files for each piece surround all their
+ code with `#ifndef ELIDE_CODE' after defining it with this:
+
+ #define OBSTACK_INTERFACE_VERSION 1
+ #if !defined (_LIBC) && defined (__GNU_LIBRARY__) && __GNU_LIBRARY__ > 1
+ #include <gnu-versions.h>
+ #if _GNU_OBSTACK_INTERFACE_VERSION == OBSTACK_INTERFACE_VERSION
+ #define ELIDE_CODE
+ #endif
+ #endif
+
+ This allows those one to avoid compiling those files when part of a GNU
+ package not libc, on a system using a GNU C library that supports the
+ same interface.
+
+ Please preserve the format of the comments after each macro. And
+ remember, if any of these versions change, the libc.so major version
+ number must change too (so avoid it)! */
