Ah, I didn't know that, thanks. Don't that pull in all the unistring modules (and code) ? At least for building the project. In libidn2 we just use a small subset of the vast functionality of gnulib unistring. In order to keep build overhead small, isn't that the way to go ? I only know that building libunistring takes a while... Regards, Tim
