After fixing the gcc warning "‘return’ with a value, in function returning
void", this code compiles perfectly fine, both with gcc and xlc, with the
configuration from [1]:

$ cat foo.c
#include <netinet/in.h>

extern int bar (uint8_t *, size_t);

int
foo(struct in6_addr *addr)
{
  return bar (addr->s6_addr, 16);
}

$ CC="gcc -maix64"; CXX="g++ -maix64"; AR="ar -X 64"; NM="nm -X 64 -B"; export CC CXX AR NM
$ $CC -Wall -c foo.c

$ CC="xlc -q64 -qthreaded -qtls"; CXX="xlC -q64 -qthreaded -qtls"; AR="ar -X 64"; NM="nm -X 64 -B"; export CC CXX AR NM
$ $CC -c foo.c

This is on gcc119.fsffrance.org (AIX 7.2). About which AIX and GCC versions
were you complaining?
