Yes. The VC2010 compiler does not support local functions. One more reason to
use gcc on MSWindows. VC2010 uses an ancient single pass concept and does not
implement all the new standards, or if it does, it diverges from the standard
just enough to make life miserable. Try writing C++ like it was 1999, and VC
may understand you better.
