2012-08-29  Basile Starynkevitch  <basile@starynkevitch.net>
	{{merging with trunk, converted to C++}}

	* melt-runtime.h (MELT_FLEXIBLE_DIM): Set when C++.

	* melt-runtime.c (melt_tempdir_path): Don't use choose_tmpdir from
	libiberty.
	(meltgc_start_module_by_index): Use address-of & on VEC_index.
	(melt_really_initialize): When printing builtin settings, handle
	GCC 4.8 as with implicit ENABLE_BUILD_WITH_CXX.
	(meltgc_out_edge): Provide additional flag TDF_DETAILS for dump_edge_info.
	(melt_val2passflag): Handle PROP_referenced_vars only when defined.

	* melt-module.mk: Use GCCMELT_COMPILER instead of GCCMELT_CC.

	* melt-build-script.tpl: Transmit GCCMELT_COMPILER on every make
	using melt-module.mk and improve the error message.

	* melt-build-script.sh: Regenerate.
