- /* 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)! */
