Rework indirect reference support as outlined by my recent message to the tech-userlevel mailing list. 1994-12-13 01:41:50 +03:00			`/*`

Changed name of __weak_reference() to __indr_reference(). They really are indirect references, and I want to add a real __weak_reference() macro to <machine/cdefs.h> soon. 1995-03-23 22:58:48 +03:00			`#ifdef __indr_reference`

Split each function in err.c out into its own file. This is needed for systems without weak or indirect references. 1996-04-16 03:44:53 +04:00			`#else`

"Fix" the non-__indr_reference verions of the user-callable versions of these functions. This is somewhat of a kludge, but there is not much else we can do for this case. Because of how the callable versions are created, by CPP trickery and inclusion of another .c file, we cannot allow the included .c file to pull in "namespace.h", since it undoes the CPP trickery we have performed. Introduce a CPP macro that prevents the included .c file from pulling in "namespace.h". 1997-07-18 01:33:14 +04:00			`#define __NO_NAMESPACE_H /* XXX */`

make libc work again, on systems that don't support __warn_reference 1994-12-18 14:32:37 +03:00			`#endif`
