I am using Boost test library now and find there are several libraries there: 

libboost_unit_test_framework-mgw46-1_47.a 
libboost_unit_test_framework-mgw46-mt-1_47.a 
libboost_unit_test_framework-mgw46-s-1_47.a 

what are differences between the 3 libraies (with "s", or with "mt", or no "mt" and "s")? 

also, for VC++ compiler, there is: 

boost_unit_test_framework-vc100-mt-1_47.dll 

but MinGW have: 

libboost_unit_test_framework-mgw46-mt-1_47.dll 
libboost_unit_test_framework-mgw46-1_47.dll 

Why MinGW have more?
