-In particular, the build system assumes that you have ELF shared

+PORTABILITY INFORMATION
+
+You will find that adns requires a reasonably standard and up to date
+system. Systems which are neither GNU nor UNIX are not supported.
+
+The build system assumes by default that you have ELF shared
+libraries, and that the directory in which libadns.so.1 will be
+installed is on your dynamic library search path. If your system
+doesn't have ELF shared libraries then dynamic linking is not
+supported by adns. Use the --disable-shared configure option.
+Please don't send me patches to use libtool (which I dislike).
+
+Compilers other than GNU C should work, but are not well-tested. Feel
+free to send me patches to improve the situation. However, the
+Makefiles only know how to use GCC to make dynamic libraries.
