I guess I found the reason why x86_64-w64-mingw32-gcc can't locate pthread.h. It's because a macro #if HAVE_PTHREAD #include <pthread.h> is used in source files, but the macro is not defined by mingw, about which I found it existiing before according to google search. I re-built it after the macro was commentted, and pthread.h was in. How is your thinking?
Another, I added -v and dependency output showed usr\x86_64-w64-mingw32\sys-root\mingw\include was in. So the search path mechanism is not a problem.
