numeric_limits<> as implement in bcc56 provides values that
are not useable as template paramters, and can not be assigned
at compile time to enums.  eg in variate_generator have_int is
always 0 and want_int is always 1 (even if at runtime they
have the correct values).

Would a borland only version (attatched) that used
boost::is_integer be acceptable ?
