[boost] BitSet and Integers

From: Dr MaaTt (dr.maatt_at_[hidden])

is there a way to turn a regular (unsigned long) integer into bitset? for
example,
unsigned long int a=1234567890;
boost::dynamic_bitset<> b(32);

can I do something similar to
boost::dynamic_bitset<> b(32, a);
or
b |= a;
without resorting to xxxUL etc?
at the moment I am doing
for( int i=0 ; i< 32 ; i++ ) if( (a & (1UL << i) ) ) b.set(i);

Thanks
