Subject: 	* alpha.c (alpha_Instruction): Don't use. 
 (alpha_find_call): Avoid use of bitfields and casts between 	pointers and
 integers of different sizes.  Avoid endian problems 	when cross-compiling. 
 * vax.c (vax_find_call): Likewise. 	(struct modebyte): Don't use. 
 (vax_operandmode): Pass in an unsigned char *. 	(vax_operandlength):
 Likewise. 	(vax_reladdr): Rename to vax_offset and return relative offset
 	rather than address. 	* i386.c (i386_find_call): Avoid casts between
 pointers and 	integers of different sizes. 	* sparc.c (sparc_find_call):
 Likewise.  Avoid endian problems. 	* tahoe.c (tahoe_find_call): Likewise.
 	(tahoe_reladdr): Rename to tahoe_offset and return relative offset 
 rather than address.

	* basic_blocks.h: Don't include headers here.
	* call_graph.h: Likewise.
	* cg_arcs.h: Likewise.
	* cg_print.h: Likewise.
	* corefile.h: Likewise.
	* gmon_io.h: Likewise.
	* gmon_out.h: Likewise.
	* hertz.h: Likewise.
	* hist.h: Likewise.
	* source.h: Likewise.
	* sym_ids.h: Likewise.
	* symtab.h: Likewise.
	* gprof.h: Don't include ansidecl.h, do include bfd.h.
	(bool): Don't typedef.
	* alpha.c: Adjust #include's for above header changes.
	* basic_blocks.c: Likewise.
	* call_graph.c: Likewise.
	* cg_arcs.c: Likewise.
	* cg_dfn.c: Likewise.
	* cg_print.c: Likewise.
	* corefile.c: Likewise.
	* gmon_io.c: Likewise.
	* gprof.c: Likewise.
	* hertz.c: Likewise.
	* hist.c: Likewise.
	* i386.c: Likewise.
	* mips.c: Likewise.
	* sparc.c: Likewise.
	* sym_ids.c: Likewise.
	* symtab.c: Likewise.
	* tahoe.c: Likewise.
	* utils.c: Likewise.
	* vax.c: Likewise.

	* po/POTFILES.in: Regenerate.
