23: /* This file exists to define these few macros.  Each specifies a version
24:    number associated with the library interface of a piece of the C library
25:    which is also distributed with other GNU packages.  These pieces are
26:    both part of the GNU C library and also distributed with other GNU
27:    packages so those packages may use their facilities on systems lacking
28:    the GNU C library.  The source files for each piece surround all their
29:    code with `#ifndef ELIDE_CODE' after defining it with this:
30: 
31:    #define OBSTACK_INTERFACE_VERSION 1
32:    #if !defined (_LIBC) && defined (__GNU_LIBRARY__) && __GNU_LIBRARY__ > 1
33:    #include <gnu-versions.h>
34:    #if _GNU_OBSTACK_INTERFACE_VERSION == OBSTACK_INTERFACE_VERSION
35:    #define ELIDE_CODE
36:    #endif
37:    #endif
38: 
39:    This allows those one to avoid compiling those files when part of a GNU
40:    package not libc, on a system using a GNU C library that supports the
41:    same interface.
42: 
43:    Please preserve the format of the comments after each macro.  And
44:    remember, if any of these versions change, the libc.so major version
45:    number must change too (so avoid it)!  */
