Hrm.  Does cpp's "#if[n]def" construct work with C defined functions?
i.e. does:

static inline int ipv6_addr_loopback(const struct in6_addr *a)
{
	return ((a->s6_addr32[0] | a->s6_addr32[1] |
		 a->s6_addr32[2] | (a->s6_addr32[3] ^ htonl(1))) == 0);
}

provide cpp with a "ipv6_addr_loopback" definition such that cpp can
test for it?

My test says no:

$ cat /tmp/a.c
static inline int foo()
{
	return 0;
}

#ifndef foo
static inline int foo()
{
	return 0;
}
#endif

main() {
}
$ gcc -o /tmp/a{,.c}
/tmp/a.c:8: error: redefinition of ‘foo’
/tmp/a.c:3: error: previous definition of ‘foo’ was here

Maybe I am misunderstanding the proposed solution?
