            Bug ID: 64812
           Summary: [4.9 regression] x86 LibreOffice Build failure:
                    undefined reference to acquire
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: regression
          Assignee: unassigned at gcc dot gnu.org
          Reporter: lukebenes at hotmail dot com

LibreOffice 4.2 or newer fails to build in a clean build environment on Linux
x86-32 with gcc 4.9.0, 4.9.1, and 4.9.2. However, the build succeeds on an
otherwise identical x86-64 system, and it also succeeds with gcc 4.8.2 (on
x86-32 and x86-64). The build also succeeds with clang 3.4 (on x86-32 and
x86-64).

The same errors appear in two places (svx and dbaccess), both times referring
to classes from toolkit/source/helper/listenermultiplexer.cxx, which compiled
fine without warnings.

Steps to reproduce on x86 NOT x86-64:
1. $ git clone git://anongit.freedesktop.org/libreoffice/core
2. $ git checkout libreoffice-4-4-0 (optional, master fails with same errors)
3. $ apt-get build-dep libreoffice ( also lo_usefull Shell Script if missing
dep)
4 ./autogen.sh && make
