Compiling example mbox under Windows problem: error C2784: '_RanIt1::difference_type std::operator

[tester0077]

The statements:
Line 155 it = utils::find_bm(bit, eit, "From ");
Line 156 if(!isnl(*(it-1))) >>>>> error C2784: '_RanIt1::difference_type std::operator ......

If I comment out line 156, I get the error
D:\pkg\C++\MSVC2010\mimetic-master\mimetic/utils.h(88): error C2664: 'mimetic::utils::find_bm' : cannot convert parameter 4 from 'std::input_iterator_tag' to 'const std::random_access_iterator_tag &'
1> Reason: cannot convert from 'std::input_iterator_tag' to 'const std::random_access_iterator_tag'
1> No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called

I am unfamiliar enough with STL & mimetic to be able to resolve this issue on my own.
FWIW, using current mimetic-master from github
