Thank you for contributing the patch.  I've placed it in here (with a
link to this message added as a comment before the actual patch):

ftp://ftp.openwall.com/pub/projects/popa3d/contrib/patches/

I think that this is a bit too much of a special case to link to the
patch from the popa3d homepage, and the patch is trivial.

This is fine, but I'd use memcpy() here.  strncpy() is almost never the
right choice because of its weird semantics - NUL padding (which is
slow), but no guaranteed NUL termination.  Most of the time, when I
write portable code, I use strncat() instead (not forgetting to set the
first character of the target buffer to NUL and to subtract 1 from the
buffer size).

Thanks again,

Alexander
