Hi Uwe and Eli. I do not know well enough what version of the compiler and the libraries are the officially accepted. In my private builds I tend to use the most updated stable version I can find, the same with the compiler. So, for future reference to the list, please, could you specify: 1) - Preferred compiler version? 2) - With/without libxml2 included? AFAIK In Emacs 24.2 official windows binaries, libxml2 was left out. ( http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00304.html ) 3) - Should every dependent library be recompiled with the chosen version of the compiler, or left as is distributed? 4) - Different configure options? From your last post, I will asume GnuTLS 3.0.9 and libxml2 2.7.8 included, but I would like answers/discussion of 1), 3) and 4). I have no problems in making another build with the official specifications. Miguel.
