Why can't gcc-4.2.1 build usable libreoffice?

Versions of gcc after the 4.2.1 version we use are licensed under GPLv3.
I'm not a lawyer, so I don't understand all the fine details of why
GPLv3 is bad for the freebsd project, but I accept the analysis and
decisions the project made on that subject some time ago.  

As you might imagine, switching to a new compiler isn't something you
decide to do this afternoon and finish up tomorrow with a big checkin.
It takes many months of testing and iteratively fixing bugs... bugs
found in the new compiler, and bugs the new compiler exposes in the
existing source base.

I think we've been able to cherry-pick a few specific fixes from gcc
upstream that weren't encumbered by GPLv3, but for the most part I think
nobody is actively maintaining the GPLv2 code anymore.
