* Makefile.in (toplev.o, halfpic.o): Depend on halfpic.h * i386/osfrose.h (SUBTARGET_SWITCHES): Add missing comma. (FUNCTION_PROFILER): Const-ify. * halfpic.c: Include "expr.h", "output.h" and "halfpic.h". (eliminate_constant_term, assemble_name, output_addr_const): Remove declarations. (ptr_half_pic_address_p, half_pic_hash): Prototype. (all_refs, half_pic_prefix, half_pic_hash, half_pic_declare, half_pic_external, half_pic_address_p, half_pic_ptr): Const-ify. * halfpic.h (ptr_half_pic_address_p, half_pic_finish): Prototype. (half_pic_declare, half_pic_external): Const-ify. * toplev.c: Include "halfpic.h". From-SVN: r46583
