Fix is already in the repository, but I'm affraid no nightly build for Windows is available.
The easies DIY fix is adding:
__cplusplus 201103L
__GXX_EXPERIMENTAL_CXX0X__ 1
to Your project/compiler #defines tab, so the CC will include C++11 features when parsing headers.
GCC 4.8.1 doesn't recognise c++11 standard as experimental anymore and that's what causes this issue, since Code::Blocks parser was expecting only experimental headers.
