Hi folks, John (Octave author) and I (.deb maintainer) need help with a build error of the latest octave on s390. Could you provide some insights?

It doesn't directly reference any ostream::write function (there is not even the string write in the program). I can compile it with g++-2.95, g++-3.0, and g++-3.2 on my x86 system. Can someone with access to an s390 system please try to debug what is happening? There is also another problem with configure on s390, but it would not affect the failure to compiler gethelp.cc: checking C++ ABI version used by /usr/bin/g++... ./configure: line 1: conft= est.o: command not found =2E/configure: line 1: conftest.o: command not found =2E/configure: line 1: conftest.o: command not found unknown How can I get access to the config.log file?
