Using llvm from trunk at revision 67301.

clang version 1.0 based upon llvm 2.6svn hosted on amd64-portbld-freebsd7.1

Using clang-driver to compile Ruby 1.9.1-p0 from ports (lang/ruby19), I get
this while compiling vm.c:

clang-driver -O -pipe  -O2 -g -Wall -Wno-parentheses  -fPIC -I.
-I.ext/include/amd64-freebsd7 -I./include -I.  -DRUBY_EXPORT   -o vm.o -c vm.c
In file included from vm.c:16:

I get the same error using the ruby 1.9/trunk
