Use std::search() to implement find_bm() instead of using a local implementation of Boyer-Moore. Avoids integer overflow reported in issue tat#31 and PR tat#31. Should fix build problem in issue tat#7. std::search is also faster for the test program in issue tat#31 on a system with an Intel Xeon E-2224 CPU: - gcc 8.5, find_bm(): 3.16s - g++ 8.5, std::search: 2.40s - g++ 13, std::search: 2.16s Experiments using the C++17 std::boyer_moore_searcher or std::boyer_moore_horspool_searcher were also slower than std::search in this experiment.

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
