On 9.1-RELEASE i386, editors/libreoffice built with clang doesn't run at all.
Built with lang/gcc46 runs OK.
(On amd64 machines, this problem doesn't appear.)
Old style WITH_GCC option is left in Makefile.
It should migrate to optionsNG.
Fix: Apply attached patch.
Patch attached with submission follows:
How-To-Repeat: Build libreoffice on i386 machine and try running.
Over to maintainer (via the GNATS Auto Assign Tool)
clang-3.2_4 has corrected the problem.
