Some statics are now defined by configure.ac.in, conky.h got a lot smaller, which I see as a positive sign. This patch should not change any functionality, just change what's defined where. Some features I did/could not test are probably broken, also compiling for any other OS surely won't complete now. Though I think fixing these problems is as easy as including some missing headers. I've done compile checks with the following configure options: ./configure --enable-eve --enable-rss --enable-smapi --enable-wlan --enable-debug --enable-testing So what needs to be tested is: - audacious - BMPx - xmms2 - nvidia
