+TESTED PLATFORMS
+
+The following platforms have been tested at at least some point and
+should work - please report if they don't:
+ adns version OS
+ 1.0 Linux glibc 2.1 (actually tested on Debian 2.2)
+ 1.0 Solaris 2.6, 2.7, 2.8 [3]
+ 1.0 FreeBSD 3.2, 4.0 (no poll(2), so no adnsresfilter)
+The following work, but only with --disable-dynamic:
+ 1.0 IRIX 6.5 *not* with GCC [1], [2]
+ 1.0 AIX 4.1.5
+ 1.0 HP-UX 10.20, 11.00
+Later versions of the same OS should work too. Usually entries in
+this table mean adns passes its own regression test, when compiled
+with GCC, and appears to install and run correctly. If you have more
+information for this table please let me know.
+
+Notes/known problems:
+ [1] IRIX 6.5 inet_ntoa seems to break with GCC.
+ [2] The SGI IRIX compiler produces many spurious warnings.
+ [3] Dynamically linked, needs some help to find libadns.so.1.0.
