logging_ok:
  Logging to logging@openlogging.org accepted
mi_packrec.c:
  Using HAVE_SYS_MMAN_H to protect include of sys/mman.h and replaced calls to mmap and munmap with my_mmap and my_munmap
mi_extra.c:
  Now using HAVE_SYS_MMAN_H to protect include of sys/mman.h
my_mmap.c:
  Changed how no mmap message is printed for Windows
sql_map.cc:
  Changed HAVE_MMAP to HAVE_SYS_MMAN_H and replaced calls to mmap and munmap with my_mmap and my_munmap
