Recently giflib made a new update, after a long time, from 5.1.4 to 5.1.5, it didn't have any impressive at first, fixing a few bugs then i read this.
Build Fixes ----------- The horrible old autoconf build system has been removed with extreme prejudice. You now build this simply by running "make" from the top-level directory.
I thought to myself, oh nice, it makes stuff simpler, less packages for us to install to build the package means reduced build times and since we just build and install we don't need incremental compiling and all that other nice stuff.
My other side went, it is extremely easy to fuck up Makefiles though, let's hope they did their homework.
