i agree

k&r defines an "int" as the "natural integer size of the architecture".
the space saving introduced by many of the u8_t/u16_t variables is really
not worth the effort IMO and creates alignment problems also.

in my code i redefine err_t to int also

at another level LwIP should have a plug-in memory allocator
so that you can use any memory allocator you like. another package
that does this is the zlib library for example.
