From 5063daf7357ccdc2c9e899ca0421c2e8e580c88d Mon Sep 17 00:00:00 2001
From: Nick Clifton <nickc@redhat.com>
Date: Thu, 27 Feb 2014 14:09:29 +0000
Subject: This patch adds a default manifest in to the final links performed by
 the Cygwin and MinGW targets. The manifest is necessary in order for the
 linked binaries to be executed in a Windows 8 environment.

The manifest is added using a linker script so that this feature will be compiler-neutral.  The resource
merging code in the linker means that if an application provides its own manifest then the default
manifest will be ignored.

	* configure.in (all_emul_extra_binaries): New variable.  Populated
	by invoking configure.tgt.
	(EMUL_EXTRA_BINARIES): New substitution.
	* configure: Regenerate.
	* configure.tgt (target_extra_binaries): New variable.  Set to
	default-manifest.o for Cygwin and MinGW targets.
	* Makefile.am (EMUL_EXTRA_BINARIES): New variable.  Initialised
	by the configure script.
	(ALL_EMUL_EXTRA_BINARIES): New variable.
	(default-manifest.o): New rule to build the default manifest.
	(ld_new_DEPENDENCIES): Add EMUL_EXTRA_BINARIES.
	(install-data-local): Add EMUL_EXTRA_BINARIES.
	* Makefile.in: Regenerate.
	* ld.texinfo: Document default manifest support.
	* emulparams/i386pe.sh (DEFAULT_MANIFEST): Define.
	* emulparams/i386pep.sh (DEFAULT_MANIFEST): Define.
	* emultempl/default-manifest.rc: New file.
	* scripttempl/pe.sc (R_RSRC): Include DEFAULT_MANIFEST, if defined.
	* scripttempl/pep.sc (R_RSRC): Likewise.

	* ld-pe/longsecn-1.d: Allow for extra sections.
	* ld-pe/longsecn-2.d: Likewise.
	* ld-pe/longsecn.d: Likewise.
	* ld-pe/secrel.d: Likewise.
