(c-lang.o): Depend on langhooks.h. (c-common.o): Don't depend on tree-inline.h. (tree-inline.o): Depend on toplev.h. (langhooks.o): New rule. * c-common.c: Don't include tree-inline.h. (c_mark_lang_decl): Mark argument c as unused. (c_common_lang_init): Don't initialize hooks here. * c-lang.c: Include langhooks.h, then override some macros. (lang_hooks): Initialize with macros in langhooks.h. (c_init): Don't initialize hooks here. * toplev.c (struct lang_hooks_for_tree_inlining): New struct. (struct lang_hooks): Add tree_inlining. Refer to langhooks.h. * tree-inline.c: Include toplev.h. Don't define hook variables. * tree-inline.h: Don't define hook types nor declare hook variables. Move macros to... * langhooks.c: ... new file, as functions. Adjust all callers.
