--- Comment #7 from Javier <javier_3 at runbox.com> ---
And of course I am compiling with -fms-extensions. Dind't you read my latest
message? I said they are turned on by default when using Clang on Windows. How
else would it compile without errors with -O0 or -O1? Here is the clang
invocation as reported by clang with the -v option:

-cc1 -triple i686-pc-windows-msvc -emit-obj -disable-free -main-file-name
ATfileinput.th -mrelocation-model static -mthread-model posix -fmath-errno
