I neglected to mention: there are two areas in the <netinet/in.h> header file
which define that same structure, with different member names and different
definitions of the macros. One uses a u8_ naming on the right hand sides of
the macro.

No problem case:

kaz at gcc119:[/home/kaz]echo '#include <netinet/in.h>
foo->s6_addr' | gcc -E - | tail -3
foo->
# 2 "<stdin>" 3 4
    u6_addr.u6_addr8

Repro case:

kaz at gcc119:[/home/kaz]echo '#include <netinet/in.h>
foo->s6_addr' | gcc -E - -D_XOPEN_SOURCE=500 | tail -3
foo->
# 2 "<stdin>" 3 4
    s6_addr.s6_addr.s6_addr8
