When building version 0.9.0 or 0.9.1 of the videolan client application with
gcc-4.3.2 or the 20080904 snapshot of version 4.3 I get the following error:

Both versions of gcc were configured as follows:
$ gcc -v
Using built-in specs.
Target: i386-pc-linux
Configured with: ../configure --prefix=/usr --infodir=/usr/info
--mandir=/usr/man --enable-shared --disable-static --with-system-zlib

Thread model: posix
gcc version 4.3.3 20080904 (prerelease) (GCC)
The application builds successfully with gcc-4.2.5-20080820 and gcc-3.4.6. It
also builds successfully if I omit the -O2 argument.
I'll attach the preprocessed file that triggers the problem in a moment or two.
