Should not a pre-C++11 compiler simply /fail/ upon encountering C++11 code?

I can not find any :-( The ones against FreeBSD 
<http://www.freebsd.org/cgi/query-pr-summary.cgi?category=&severity=&priority=&class=&state=&sort=none&text=libreoffice&responsible=&multitext=&originator=&release=> 
all talk about build failures (except the 176269 
<http://www.freebsd.org/cgi/query-pr.cgi?pr=ports/176269>, filed today). There 
are no relevant bug-reports against LibreOffice, that mention "gcc-4.2.1" 
<https://bugassistant.libreoffice.org/buglist.cgi?quicksearch=gcc-4.2.1> or "gcc 
4.2.1 <https://bugassistant.libreoffice.org/buglist.cgi?quicksearch=gcc%204.2.1>".
