+The following platforms have been tested at at least some point and
+should work - please report if they don't:
+ [adns] OS
+ pre-1.0 Linux glibc 2.1 (actually tested on Debian 2.2).
+ pre-1.0 FreeBSD 3.2
+ pre-1.0 Solaris 2.6, 2.7, 2.8
+ pre-1.0 HP-UX 10.20, 11.00
+ pre-1.0 IRIX 6.5 *not* with GCC [1], --disable-dynamic
+Later versions of the same OS should work too. [adns] is the latest
+version of adns that has been tested. Usually entries in this table
+mean they pass adns's own regression test, when compiled with GCC.
+Notes/known problems:
+ [1] IRIX 6.5 inet_ntoa seems to break with GCC.
+
+The following platforms are known to be deficient and will not work:
+ Solaris 2.5 Lacks vsnprintf
+Please don't report these problems unless you have a nice,
+straightforward solution or workaround for them.
