The other recent bug is about ftp not working out of the box on GNU Emacs= =20 binary for Windows downloaded from FSF site, whereas Lennart's EmacsW32=20 distribution includes a Open source ftp binary that fixed the problem. I feel that it would be great for all features of emacs work out of the b= ox=20 as much as possible for platforms that are supported by FSF. Since FSF does develope a version of emacs that works for Windows... i do= n't=20 understand if there is a reason to not include these DLLs? The only reason i can think of is that perhaps FSF prefer emacs to be wor= k=20 well for GNU/Linux and does not take extra steps to make it work as well = for=20 =E2=80=9Cnon-free=E2=80=9D Windows. If this is the reason to not include = image library DLLs=20 for Windows, i feel this perhaps damaging to the spread of FSF philosophy= ,=20 since many Windows people who tries emacs and just find it not working in= =20 many situations. For example, Visual Basic and PHP today are perhaps the=20 most used languages if one count the pencentage of number of programers f= or=20 these langs. btw, I should mention this message is just meant to address this image dl= l=20 issue pertaining this bug report, not meant to argue about philosophy or=20 best approach to FSF philosophy. I feel that a binary version of Emacs fo= r=20 Windows downloaded from FSF's official site and not able to open image fi= les=20 is something like a show-stopper bug. Thanks.
