long double support in Boost.Math is deliberately disabled for Borland: 
although the compiler supports the 80-bit long double data type, last time I 
checked all the std lib long double functions just forward to the double 
versions which breaks all the internal assumptions the library makes about 
what will cause over/under flow etc.
