Yes, I had seen it but haven't volunteered my build machines because the
build servers download code to execute over the open internet using only 
an rsync server, which gives no assurance that it hasn't been spoofed.
Hopefully after the rsync server over SSH patch is integrated we can use
that and I won't worry any more.

Here's more fixes to build on three more platforms:

    1. remove AC_FUNC_MEMCMP from configure.in because it causes Sunos
	4.1.4 to die.  memcmp() there fails the "8-bit clean" test, but it
	doesn't matter because memcmp() in rsync is only used to test if
	something is equal or not equal, not to compare if it is less or
	greater.  AC_FUNC_MEMCMP has always been in configure.in but before
	now it has been ignored because @LIBOBJS@ was not used in
	Makefile.in now and that was the only thing it affected.

    2. Amdahl's UTS 2.1.2 defines NO_ADDRESS instead of NO_DATA.

    3. Sunos 4.1.4 and Unixware 1.1.2 don't have stderr defined in unistd.h.
	Note: I see that rsync.h has an #ifdef HAVE_UNISTD_H around including
	unistd.h, perhaps it would be better to include rsync.h instead of
	most of the includes at the beginning of getaddrinfo.c

    4. Unixware 1.1.2 and UTS 2.1.2 had missing S_ISLNK and S_ISSOCK
	macros which are defined in rsync.h.  Maybe all the lib files
	should just include rsync.h.
