This is way it is currently not marked as serious. It doesn't affect the
release of the next debian version, but all these things could break in the
future. I am willing to gather more informations in the wiki but currently
don't know how.

I have only build some packages. I have currently following numbers:
50 Packages break
555 Packages work (without arch all)
As you can see I have only data for about 7% of all packages so I cannot make
a real forecast how many packages are real affected. If you want to
extrapolate the data (real bad extrapolation) about 700 packages of around
14000 source packages in Debian would break. I am currently hoping that they
are less than that. Some packages in the statistics seems to be also broken
with the current ld - avifile seems to be one of them. The author is currently
waiting for a sponsor to fix that problem.
To illustrate the problem:
exe -> liba -> libb
exe gets linked against liba, but actual need symbols from libb. It works in
the case of the old GNU ld because it loads all libraries in that dependency
graph until it finds the symbols. This seems to be ok unless liba gets
modified and doesn't link anymore against libb. In this case the compilation
stops during the linker run.
Keep in mind that these bugs aren't release critical, but the maintainer and
upstream should know about these problems. Maybe I could reduce the problem of
all bugs to minor.
About the usertags? Is there a special format in which they should be? And a
maintainer asked for a wiki entry at
http://wiki.debian.org/qa.debian.org/FTBFS but I am not allowed to change that
patch - and I am sure that I shouldn't be allowed to edit it.
Best regards,
Peter
