Can you under the GPL distribute executables without full sources?

Thanks for your comments.
Let me clarify the points :
The DIA tool is a GTK(+) based diagram tool.
It has been ported to the windows by Hans Breuer and Tor Lillqvist.
After looking into it, The source code is not exactly broken, just
There are a bunch of needed dlls,
gdk-1.3.dll gdk_imlib.dll glib-1.3.dll gmodule-1.3.dll gnu-intl.dll
gthread-1.3.dll gtk-1.3.dll iconv-1.3.dll imlib-gif.dll imlib-jpeg.dll
imlib-png.dll imlib-tiff.dll libart.dll libgdk-0.dll
libgdk-pixbuf-0.dll libglib-2.0-0.dll libgmodule-2.0-0.dll
libgthread-2.0-0.dll libgtk-0.dll libxml2.dll pthread.dll
That are all distributed with the executable.
Some of them are as old as march 21 2000!
Others as new as new as June 1 2001.
Some of these have the source code on tors site, some on hans,
others not at all. Some are in the gnome cvs, others in the gnu cvs.

Maybe people have complained about that state of the compilation.
Worse, the way that the port has been setup, people will tend to just
download the ready made development libs and dlls, that are on the
site, but not the source code that is not there.

It was not indended on being broken,
the statement is that the code can be compiled, given lots of work and

The GTK will not count either.

Sure, but you cannot distribute a binary without having the source
if you get the exec, you need to have the source available. You need to
get a copy of the license.
If you then redistribute the binary that is not GPL compatible,
you are in a no-mans land.
Plus the gettext is FSF copyleft and GPL, and all these tools are
derived including this.
