libcmis i386 build fail

Hi,

I had this libcmis build fail on i386 today:

 
https://launchpadlibrarian.net/124428787/buildlog_ubuntu-raring-i386.libcmis_0.3.0-1~ubuntu1~ppa1_FAILEDTOBUILD.txt.gz

and assume the attached patch would fix that. Please consider for inclusion.
(Sending a patch, as fdo is down and libcmis is not on gerrit).

NB: The patch is totally untested.

Best,

Bjoern
