From 3e1e123d02fa495961898f390741bd743a92022d Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Fri, 11 Feb 2005 10:17:19 +0000 Subject: [BZ #715] * Makefile (installed-stubs): New variable. Set to $(inst_includedir)/gnu/stubs.h if $(biarch) is no, or to $(inst_includedir)/gnu/stubs-$(biarch).h if otherwise. [$(biarch) != no] (install-others-nosubdir): Add $(installed-stubs). ($(inst_includedir)/gnu/stubs.h): Use $(installed-stubs) for this rule's target. ($(inst_includedir)/gnu/stubs.h): New target, install from ... * include/stubs-biarch.h: New file. * shlib-versions (i.86-.*-.*): Add WORDSIZE64 line mapping to x86_64. * Makeconfig ($(common-objpfx)soversions.mk): Depend on Makeconfig.
