Running mingw is really hard due to path issues. Here's what I do to 
configure regressions runners:

I install a Mingw-w64 compiler. Say in:

C:\Programs\mingw-builds\i686-7.1.0-posix-dwarf-rt_v5-rev2\

then I put a file named gcc-7.1.bat in:

C:\Programs\mingw-builds\i686-7.1.0-posix-dwarf-rt_v5-rev2\mingw32\bin\gcc-7.1.bat

The .bat file contains the commands:

@echo off
set 
PATH=C:\Programs\mingw-builds\i686-7.1.0-posix-dwarf-rt_v5-rev2\mingw32\bin;%PATH%
g++ %*

Finally I add the compiler to user-config.jam with several c++ standard 
compliance versions:

#GCC 7.1
using gcc : 7.1c++17 : 
C:/Programs/mingw-builds/i686-7.1.0-posix-dwarf-rt_v5-rev2/mingw32/bin/gcc-7.1.bat 
: <cxxflags>"-pipe -fmax-errors=1 -std=c++17 -Wall -Wextra -pedantic 
-Wno-deprecated-declarations -Wno-long-long -Werror" <linkflags>"-pipe" ;
using gcc : 7.1c++14 : 
C:/Programs/mingw-builds/i686-7.1.0-posix-dwarf-rt_v5-rev2/mingw32/bin/gcc-7.1.bat 
: <cxxflags>"-pipe -fmax-errors=1 -std=c++14 -Wall -Wextra -pedantic 
-Wno-deprecated-declarations -Wno-long-long -Werror" <linkflags>"-pipe" ;
using gcc : 7.1c++11 : 
C:/Programs/mingw-builds/i686-7.1.0-posix-dwarf-rt_v5-rev2/mingw32/bin/gcc-7.1.bat 
: <cxxflags>"-pipe -fmax-errors=1 -std=c++11 -Wall -Wextra -pedantic 
-Wno-deprecated-declarations -Wno-long-long -Werror" <linkflags>"-pipe" ;
using gcc : 7.1c++03 : 
C:/Programs/mingw-builds/i686-7.1.0-posix-dwarf-rt_v5-rev2/mingw32/bin/gcc-7.1.bat 
: <cxxflags>"-pipe -fmax-errors=1 -std=c++03 -Wall -Wextra -pedantic 
-Wno-deprecated-declarations -Wno-long-long -Werror" <linkflags>"-pipe" ;

Then I can run tests as:

c:\Data\Libs\boost\libs\move\test>..\..\..\b2 toolset=gcc-7.1c++17

I hope it helps.
