==6225== Source and destination overlap in memcpy(0x8166A40, 0x8166A40, 10)
==6225==    at 0x1B906BCE: memcpy (mac_replace_strmem.c:113)
==6225==    by 0x80A51AE: mystrlcpy (support.c:235)
==6225==    by 0x8091378: tilespec_fullname (tilespec.c:302)
==6225==    by 0x80922DA: tilespec_read_toplevel (tilespec.c:756)
==6225==    by 0x80916CE: tilespec_reread (tilespec.c:430)
==6225==    by 0x80918C8: tilespec_reread_callback (tilespec.c:510)
==6225==    by 0x814640B: option_ok_command_callback (gamedlgs.c:393)

I think this occurs in other places though.  One solution is to use 
memmove in mystrlcpy.
