I think this is a known problem of the Newlib/GCC build. During the 
libgcc build the default header files are picked up, e.g.

newlib/libc/include/sys/_pthreadtypes.h

later during Newlib build, some header files are copied into the build 
tree. Then a copy of

newlib/libc/sys/rtems/include/sys/_pthreadtypes.h

is used (nios2-rtems5/newlib/targ-include/sys/_pthreadtypes.h).

I made several attempts to fix this, but its quite convoluted. You 
change one thing, and it breaks another thing.
