egcs/ChangeLog:
1998-06-24  Manfred Hollstein  <manfred@s-direktnet.de>
	* configure (enable_version_specific_runtime_libs): Implement new flag
	--enable-version-specific-runtime-libs which installs C++ runtime stuff in
	$(libsubdir); emit definition in each generated Makefile.
	(gxx_include_dir): Initialize depending on $enable_version_specific_runtime_libs.
egcs/gcc/ChangeLog:
1998-06-24  Manfred Hollstein  <manfred@s-direktnet.de>
	* configure.in (gxx_include_dir): Initialize default value depending on
	new flag --enable-version-specific-runtime-libs; remove superfluous default
	initialization afterwards.
	* configure: Regenerate.
egcs/libio/ChangeLog:
1998-06-24  Manfred Hollstein  <manfred@s-direktnet.de>
	* Makefile.in (install): Install _G_config.h depending on new flag
	--enable-version-specific-runtime-libs.
	* config/linux.mt (gxx_include_dir): Remove definition here as we use
	gcc's default anyway.
egcs/libstdc++/ChangeLog:
1998-06-24  Manfred Hollstein  <manfred@s-direktnet.de>
	* Makefile.in (INSTALLDIR): Add comment to document the fact,
	this macro will be properly initialized at make's runtime.
	(install): Add initialization of INSTALLDIR depending on $(libsubdir)
	and ${enable_version_specific_runtime_libs}; use $${INSTALLDIR} shell variable
	instead of the $(INSTALLDIR) make macro.
