Chuck, about two month ago we had a private discussion about the file_magic
stuff, where i have investigated about 7 hours to figure out a faster approach
for identifing import library file types, because the implementation you have
mentioned would increase the kde compiling time more than about 70 % (that means
6,8 hours instead 4 hours for a full recompile, which is inacceptable  for me).
Probably you remember this stuff, if not I can send you the thread. So it seems
to me, that you only like to get my confirmation about your solution and nothing
else.

For example:
>I realize that ANY slowdown is painful, but at least these checks are

This may be true for small applications and with small number of dll's but not
for kde as it
contains about 200 dll's and 100 exe's. (see timing example above)

May be you'r right with your point of view, but this would throw back me very
much, so I had decided to stop this thread. (I'm using pass_all currently, it
works for me)

Instead I begun to think about how to solve this problem in a general way and
the result is the auto-import-from-dll-stuff (probably you don't know this
cause), so this may not be wath you have expected, but think about if this isn't
also a good contribution.

Additional you know that the libtool is very complicate and someone need very
deep knowledge about this stuff to handle with this. At that time I couldn't
investigate more time to enter the same knowledge level as you to give a
qualified answer.
In the last two weeks I've started fixing the kde3 build system and have to go
very deeply into libtool and friends, so now I'm feeling comfortable again with
this stuff and so I could give the above mentioned input and that probably for a
time windows of about the next month. not earlier, sorry. This is reason for the
contribution right now.

Third, I have stated more than one time, that kde uses an older libtool/automake
(kde3 for example libtool 1.4e, automake 1.5/1.6) release and so following the
on-going process makes not very much sense for me (because of limited time).
Instead I have to fix bugs in that releases and from the growing knowledge I can
give input.

Fourth: Chuck, the problem in the last two month was, you haven't asked, if I
have time for handling this, you only have started some threads and requested
like "... need input" and you have expected, that I have the libtool knowledge
all the days, which isn't true. If you would have asked, I would have said:
Please wait until I'm going to the kde3 build fix and than I can help. Sorry.

Fifth: I have never seen a man like you, who is able to write so very detailed
and deals so fast with such complicated stuff, that sometime a lamp goes on,
which is named "overload". :-)

Regards

Ralf
