[lwip-users] structure packaging

[mgroups]

Hello,

I'm using lwip on a LPC2378 from NXP in a single-threaded environment.
My IDE is Keil uVision 4 with the Realview compiler.
I had some problems with structur packaging.

There are some structures that are by default not packed but only work 
if they are packed.
The following structures are:
struct mem in mem.c
struct pbuf in pbuf.h
struct dhcp in dhcp.h

Is there any reason that they are not packed by default? Because I think 
they should be.
Has anyone had similar problems?

Yours
Matthias
