Yes, multiple -Werror,-Wunknown-pragmas caused by my

"Does that help old GCC that don't know -Wplacement-new."  (And it is 
normal behavior that the compiler quits with a "too many errors" message 
when it has encountered a large amount of errors in a compilation, 
assuming something is so broken with that input that it doesn't make 
much sense to present ever more error messages to the user.)  This 
problem should be fixed with 
<http://cgit.freedesktop.org/libreoffice/core/commit/?id=dda3fc05a2900539836f9748d418dc56247a2ddc> 
"Fix for Jenkins Gerrit Mac builds."

What is worrying is that this problem only showed up in Jenkins Gerrit 
builds, not in Jenkins tinderbox builds.  The two Jenkins Mac 
tinderboxes on master, Jenkins_MacOSX and Jenkins_MacOSX_Dbg, stayed 
green after 2c9d652dc7f7a1e2d0d8ea0cfcdcf47608a3d84e.

Quoting IRC: "<sberg> shm_get_, cloph, Jenkins_MacOSX tinderbox is a 
mystery to me; in 
<http://tinderbox.libreoffice.org/cgi-bin/gunzip.cgi?tree=MASTER&full-log=1453200807.490> 
build it broke when compiling sal/cppunittester/cppunittester.cxx; 
according to <http://tinderbox.libreoffice.org/MASTER/status.html>, the 
next build of that tb was 
<http://tinderbox.libreoffice.org/cgi-bin/gunzip.cgi?tree=MASTER&full-log=1453203566.10951>, 
and that doesn't mention building sal/cppunittester/cppunittester.cxx at 
all, and succeeds; how can that be?"

(I didn't notice any problems with my local Mac builds, as I only do 
them with a trunk Clang, which does know the offending pragmas,  The 
only other Mac tinderbox on master, MacOSX_x86_64_49-TDF operated by 
cloph, appears to be down and hasn't reported any builds in quite some 
time now.)
