* Partially cleaned up prototyping code from HJ.
* haifa-sched.c (haifa_classify_insn): Renamed from classify_insn.
All references changed.
* rtl.h: Protect from multiple inclusions. Add many prototypes.
* libgcc2.c (string.h): Hoist inclusion to occur before first use of
string functions like strlen.
More pending patches.
