2009-06-26  Laurent GUERBY  <laurent@guerby.net>

	* tb-gcc.c (trace_callback): Use char* instead of void*.
	* gcc-interface/misc.c (enumerate_modes): Make loop compatible
	with C++.
	* gcc-interface/trans.c (parm_attr): Rename to parm_attr_d. 
	Change all uses.
	* gcc-interface/utils.c (new, class, template): Rename to be
	compatible with C++. Change all uses.
	* gcc-interface/decl.c (new): Likewise.
