* On Windows, we need a .lib for the .dll, and a static .lib. These, obviously, need different names. So add _static onto the name of the static lib.
* Only build the objects once, so explicitly build both with PIC.
* Only export the explicit list of symbols from the shared library. This has to be done a different way on GNU ld, Mac linker and Windows.
* Although I have left the tools being linked statically, I have tested with dynamic linking. getdns_query uses gettimeofday(), which isn't on Windows. With a static link, it just happens to find it in the getdns library, as the symbols aren't filtered. But this doesn't work for shared use, when they are. So explicitly add the compat implementation into the getdns_query sources.

First pass at adding shared libraries to the current static library build.
* I can't find out where the .so version number currently produced by the autoconf build comes from, so for the moment supply it explicitly.
* Include a version in the Windows DLL. But Windows can only grok major[.minor]. So also supply one of those.
* On Windows, we need a .lib for the .dll, and a static .lib. These, obviously, need different names. So add _static onto the name of the static lib.
* Only build the objects once, so explicitly build both with PIC.
* Only export the explicit list of symbols from the shared library. This has to be done a different way on GNU ld, Mac linker and Windows.
* Although I have left the tools being linked statically, I have tested with dynamic linking. getdns_query uses gettimeofday(), which isn't on Windows. With a static link, it just happens to find it in the getdns library, as the symbols aren't filtered. But this doesn't work for shared use, when they are. So explicitly add the compat implementation into the getdns_query sources.

First pass at adding shared libraries to the current static library build.
* I can't find out where the .so version number currently produced by the autoconf build comes from, so for the moment supply it explicitly.
* Include a version in the Windows DLL. But Windows can only grok major[.minor]. So also supply one of those.
* On Windows, we need a .lib for the .dll, and a static .lib. These, obviously, need different names. So add _static onto the name of the static lib.
* Only build the objects once, so explicitly build both with PIC.
* Only export the explicit list of symbols from the shared library. This has to be done a different way on GNU ld, Mac linker and Windows.
* Although I have left the tools being linked statically, I have tested with dynamic linking. getdns_query uses gettimeofday(), which isn't on Windows. With a static link, it just happens to find it in the getdns library, as the symbols aren't filtered. But this doesn't work for shared use, when they are. So explicitly add the compat implementation into the getdns_query sources.
