Browse source 
- fix to buildin.c to prevent compiler from optimizing it out
- fix to realpath.c to handle case where 'path' is NULL

- fix to emacs.c (I think from dgk)

- fix to file.c (I think from gsf)
- fix to tail.c (I think from gsf)

- fix to code setting the malloc init hook (for vmalloc)

- changed memcpy to memmove in several places in sfio because src and dst
  might overlap
