Request broader platform support for libpsl

[rsbeckerca]

I am trying to build libpsl on a POSIX platform other than Linux and it has issues when not using gcc. I am limited to c99. The initial build problems are as follows:

  CC       libpsl_la-psl.lo
        struct in6_addr addr6;
                        ^
"/home/randall/libpsl-0.21.5/src/psl.c", line 1611: error(163): incomplete type is not allowed

        return inet_pton(AF_INET, hostname, &addr) || inet_pton(AF_INET6, hostname, &addr6);
               ^
"/home/randall/libpsl-0.21.5/src/psl.c", line 1613: error(114): identifier "inet_pton" is undefined

2 errors detected in the compilation of "psl.c".

I cannot find inet_pton outside of very limited Linux distros. If is not in a common library. The incomplete type is probably just a missing include of in6.h. I can help with that, but intergrating with inet_pton is problematic.

I fixed the compile issue - it as actually simple - see commit 475e238 - but need DLL support, which is not according to what configure wants. I need to specify -Wshared.

This issue has been fixed in git master.
