| 22 | /* This file exists to define these few macros. Each specifies a version | |
| 23 | number associated with the library interface of a piece of the C library | |
| 24 | which is also distributed with other GNU packages. These pieces are | |
| 25 | both part of the GNU C library and also distributed with other GNU | |
| 26 | packages so those packages may use their facilities on systems lacking | |
| 27 | the GNU C library. The source files for each piece surround all their | |
| 28 | code with `#ifndef ELIDE_CODE' after defining it with this: | |
| 29 | ||
| 30 | #define OBSTACK_INTERFACE_VERSION 1 | |
| 31 | #if !defined (_LIBC) && defined (__GNU_LIBRARY__) && __GNU_LIBRARY__ > 1 | |
| 32 | #include <gnu-versions.h> | |
| 33 | #if _GNU_OBSTACK_INTERFACE_VERSION == OBSTACK_INTERFACE_VERSION | |
| 34 | #define ELIDE_CODE | |
| 35 | #endif | |
| 36 | #endif | |
| 37 | ||
| 38 | This allows those one to avoid compiling those files when part of a GNU | |
| 39 | package not libc, on a system using a GNU C library that supports the | |
| 40 | same interface. | |
| 41 | ||
| 42 | Please preserve the format of the comments after each macro. And | |
| 43 | remember, if any of these versions change, the libc.so major version | |
| 44 | number must change too (so avoid it)! */ | |
