If INITDAT isn't copied this clearly is a bug! But can you please show
me any standard paper that makes it mandatory to zero the BSS? All
compilers I use do it, but as long as I don't know it's really a
standard and not a thing most compilers do, I don't want to make it
mandatory for a portable piece of code like lwIP should be.

Don't get me wrong, my goal would be to leave the zeroing to the
compiler, only I want to be sure it's really portable!

For embedded platforms, this should definitively be achievable.
