This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.59.  Invocation command line was

  $ ./configure --prefix=/usr --prefix=/usr --sysconfdir=/etc --localstatedir=/var --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --build=i686-uhu-linux --host=i686-uhu-linux --disable-static CFLAGS=-O2 -march=i686 -mtune=generic  build_alias=i686-uhu-linux host_alias=i686-uhu-linux --cache-file=/dev/null --srcdir=.
