I've made the modification, boost.date_time compiled without any
errors but the program still has errors. In particular it complains :

boost\date_time\time_duration.hpp(61) : error C2784: '_Tp __cdecl
_STL::abs(const struct _STL::complex<_Tp> &)' : could not deduce
template argument for 'const struct _STL::complex<_Tp> &' from
'__int64' boost\date_time\time_duration.hpp(60) : while compiling
class-template member function 'long __thiscall
boost::date_time::time_duration<class
boost::posix_time::time_duration,class boost::date_time::time_res
olution_traits<__int64,4,1000000,6,long> >::minutes(void) const'

I've tried to include "cmath" in boost/date_time/time_duration.hpp...
same error. Tried with "cstdlib" same error... I think i'm missing
something...
