When trying to compile the latest FFmpeg for Win64.

Any ideas?

This bug effects the build processes and the Win64 builds can not be made until it is resolved, so I gave it critical.

[Carl Eugen Hoyos]

Compilation works fine for me with

$ gcc -v
Using built-in specs.
COLLECT_GCC=c:\mingw64\bin\gcc.exe
COLLECT_LTO_WRAPPER=c:/mingw64/bin/../libexec/gcc/x86_64-w64-mingw32/4.7.0/lto-wrapper.exe
Target: x86_64-w64-mingw32
Configured with: ../../../build/gcc/src/configure --target=x86_64-w64-mingw32 --prefix=/c/bb/vista64-mingw32/mingw-x86-x86_64/build/build/root --with-sysroot=/c/bb/vista64-mingw32/mingw-x86-x86_64/build/build/root --enable-languages=all,obj-c++ --enable-fully-dynamic-tring --disable-multilib
Thread model: win32
gcc version 4.7.0 20110827 (experimental) (GCC)
./configure && make

Please provide the exact change that introduces the regression for you (or the compilation option I am missing).
