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`
__warn_references and __indr_reference semicolon fixups. From Chris Demetriou <cgd@pa.dec.com>. 1997-11-05 02:52:05 +03:00			`__indr_reference(_err, err)`

"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 */`

#define _verr* to verr*, to make these use prototypes correctly and compile in the "no indr_references" case. 1996-04-18 03:05:44 +04:00			`#define _verr verr`
