Hi, I was trying to figure out why CDE does not want to run on some
distros, including
the latest release of Fedora. These two patches are enough to get dtwm to
run.
The first is important, because it allows ToolTalk to work which dtwm is
reliant on (without the server starting
no tooltalk reliant program seems to be able to do anything at all).
The second is a hack for issues with font loading; I'm not sure it's the
"correct" hack even.
Still this does not seem to be enough to make starting full cde work yet,
but I send these patches
since finding the cause of tooltalk issue was a big pain.
-----------------------
For this first patch, ttsession (tooltalk daemon) was looping forever
polling /etc/mtab; it turns
out this is because in some distros (Fedora) it is a symlink of size zero.
Since the infinite loop which is caused is a workaround for something
ancient, it's probably
safe to just remove.

(This patch is much sketchier)
fontList ends up being an empty list, causing dtwm to exit.
Workaround by forcing load of "fixed" font.
