Update of patch #6699 (project lwip):

                  Status:                    None => Done                   
             Assigned to:                    None => goldsimon              
             Open/Closed:                    Open => Closed                 


Follow-up Comment #2:

I've fixed some of the errors, though not all: the "Conversion may lose
significant digits" warnings in pbuf.c, mem.c and sockets.c:

lwIP relies on less stricter warnings (gcc switch -Wall only) and this
warning is NOT shown there (although truncated from int to u16_t), you may
define other warning options for your compiler.

No, it's not true. lwIP should run on all platforms since 'int' should only
be used where the size does not matter. Of course it might be that there are
some places where this is not correctly implemented, but that would be a bug
and should be reported here!
