Subject: 	* include/stdio.h: Don't include stdarg.h. 	(__VA_LIST):
 Define as __builtin_va_list or char* instead. 	* include/stdarg.h: #include
 _mingw.h. 	In C++, #include_next<stdarg.g> in namespace __ginclude. 
 Push va_list into std:: if whole file is needed, else 	push __gnuc_va_list
 into global.
