Hi, Holger, Carsten, I'm sorry, when I prepared the patch, I minimized my own effort and didn't bother to maintain compatibility with BLT 2. The problem with BLT 3 is that it isn't released yet and I don't know when it'll be released. So, currently keeping ngspice compatible with BLT 2 is a must.
Also, my patch to ngspice relies on a bugfix to https://sourceforge.net/p/blt/patches/46/ so it might be useless upstream before the patch there goes to the repository. Anyway, I'm attaching a more complete version of the patch which doesn't break compatibility with BLT 2. It might need a better way of finding blt.h in the configure script though.
