What does config.log say about the cause of your failure?

I too am trying to build Scribus 1.0, but configure is telling me I don't 
have Qt>=3.0.2.  It is lying -- I have Qt == 3.0.5 correctly installed, in 
/usr/share/qt3; ($QTDIR="/usr/share/qt3" is exported, /etc/ld.so.conf 
includes the reference to /usr/share/qt3/lib, and I invoked configure as 
./configure --with-qt-dir=/usr/share/qt3).  My config.log says ...

For more details about this problem, look at the end of config.log.
Make sure that you have compiled Qt with thread support!

Take a close look at *why* this failed.  It has choked on an invalid 
declaration for the exit function, in confdefs.h, *before* it ever got to 
test anything about the Qt installation.

Now, configure builds confdefs.h dynamically, right.  So, why is it putting 
this rogue declaration in there?  In fact, why is it declaring exit at all, 
since this is properly declared in stdlib.h in any case?

This is something which the Scribus package maintainers really need to take a 
look at;  I don't know how to fix it either.  I do know that configure itself 
is built by autoconf, using instructions from configure.in, aclocal.m4 and 
acinclude.m4;  I have had a look at them,  but the problem does not appear to 
lie there, so perhaps it is a problem with autoconf itself?

I am trying to build this on a Mandrake 8.2 system, with Qt 3.0.5 compiled 
from source, (including thread support). My compiler is GCC 2.96, and I also 
have autoconf 2.13.  Is it simply a case that I need to upgrade to a later 
GCC (and perhaps autoconf too), or is there some other issue here?

I would dearly like to get Scribus 1.0 installed, but so far I am stumped. 
Any suggestions please?
