Warning fixes:

	* cp-demangle.c (cp_demangle_type): Wrap in IN_LIBGCC2.

	* setenv.c (setenv): Initialize variable `ep'.

	* sigsetmask.c (abort): Prototype.

	* vasprintf.c: Include config.h.  Check ANSI_PROTOTYPES, not
	__STDC__ for stdarg.h include.
	(int_vasprintf): Prototype.
	(checkit): Prototype.  Use VPARAMS/ANSI_PROTOTYPES/VA_START in
	definition.  Cast `global_total_width' in comparison.
	(main): Prototype.  Return a value.

	* vfork.c (fork): Prototype.

	* xexit.c: Include config.h.
