That would be 
<http://cgit.freedesktop.org/libreoffice/core/commit/?id=65da24773fffea4e4bc81adfa265378064186488> 
"Be more picky about Mac OS X linker warnings" (which I introduced after 
fixing a similar warning with liborcus, 
<http://cgit.freedesktop.org/libreoffice/core/commit/?id=913ba61d008c6629272ba3df8d22dbff0e2dc4f9> 
"Make liborcus -fvisibility setting consistent with LO one").

Odd that this doesn't show up with my build (on Mac OS X 10.7).  What 
are the details of your build?

Anyway, you can just locally revert that -Wl,-fatal_warnings in 
solenv/gbuild/platform/macosx.mk for now.  I'll have a look later to see 
if I can reproduce your problem (and get a fix); otherwise, we'd 
exercise "Feel free to revert if it causes trouble, though."
