One can maybe extract some entropy from macros such as __DATE__ and 
__TIME__, using both preprocessing and templates.
I had another crazy idea: exploit the fact that date and time are 
separate to map the rather limited (compared to full time) range of 
possibilities.

template<const char*>
struct date
{
};

template<> struct<"Dec 4 2007">
{
     static const int month = 12;
     static const int day = 4;
     static const int year = 2007;
};

then use struct<__DATE__>.

However it seems C++ doesn't allow this either?
