Return to err.h CVS log

Up to [local] / src / include

Well, as we are heading for a release people are encouraged to rebuild their
entire trees for testing anyway, I might as well do this intrusive touching
of include files now.  Added openBSD tags.

 * Don't use va_list in the err/warn prototypes.   Va_list is typedef'd in two
 * places (<machine/varargs.h> and <machine/stdarg.h>), so if we include one
 * of them here we may collide with the utility's includes.  It's unreasonable
 * for utilities to have to include one of them to include err.h, so we get
 * _BSD_VA_LIST_ from <machine/ansi.h> and use it.
