Im also running into this problem in stage2 where it fails to find stdarg.h. As an experiment i tried reverting kai's work but it still fails to find system headers. A non bootstrap build works but im having problems with programs using libstdc++. All programs compiled that depends on libstdc++ will crash with initialization error 0xc000005. My machine is Win7 64. All previous gcc versions build fine btw. And work also. I have tried with versions compiled by other parts and the problem persists.
