| /* 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)! */ |
