This seems to be a bug in the movedata.h file. A patch is included which
corrects it. As a workaround, you can add the line
#include <sys/types.h>
before you #include <sys/movedata.h>.

You are right. That's a documentation bug. It should be fixed in the next
release.

Patch follows:

  void dosmemget(unsigned long _offset, size_t _length, void *_buffer);
  void dosmemput(const void *_buffer, size_t _length, unsigned long _offset);
