So Howard was right - BOOST_NO_STDC_NAMESPACE is defined but shouldn't be.

Look at boost/config/posix_features.hpp, around line 38:

#  ifndef __APPLE_CC__

// GCC strange "ignore std" mode works better if you pretend everything
// is in the std namespace, for the most part.

#    define BOOST_NO_STDC_NAMESPACE
#  endif

Note that this is inside an #if:

#if __MACH__ && !defined(_MSL_USING_MSL_C)

It looks to me like something is wrong with one or the other of these two 
pieces of code. But since I know nothing of the Mac OS, I won't hazard a 
guess as to the exact problem or the fix.

Mac experts?
