Hello,

this is a first, small chunk of the C++ conversion patch.
Committed as pre-approved.


libcpp/
2004-07-24  Bernardo Innocenti  <bernie@develer.com>

	* internal.h (xnew, xcnew, xnewvec, xcnewvec, xobnew): Remove.
	* directives.c: Use XNEW-family macros from libiberty.
	* lex.c: Likewise.
	* macro.c: Likewise.
	* cpplib.h (cpp_deps_style): Export enum with name.
