[lwip-devel] [bug #33485] SOCK_ADDR_TYPE_MATCH and SOCK_ADDR_TYPE_MATCH_OR_UNSPEC use error

[Bill Auerbach]

Follow-up Comment #8, bug #33485 (project lwip):

>alignment1 and alignment2 will give the required result on most
compilers,...

I agree and I would say all compilers.  My point was there could be a lot of
compiler-added padding with the extra alignments and if the sa_* members are
each aligned.  alignment1 isn't necessary.  *If* a compiler is going to align
members, alignment2 will align the follow u8_t array.  And it will also align
alignment1 wasting space.

But the statement by Simon that this is an internal type changed my worries of
a bloated ip_addr type.  I thought it might be copied a good bit in the code
if it were a global type.
