I tried to build boost 1.71.0 with minGW 6.3.0 (after a few searches I found this tutorial), apparently we can't directly build boost with mingw so I built bjam and then I ran the following command in the boost directory:
..\boost-jam-3.1.18\bin.ntx86\bjam.exe --prefix=[some-path]\boost32 toolset=gcc address-model=32 variant=debug,release link=static,shared threading=multi install
And got the following output:
[path-to-boost]/tools/build/src/tools/types\adoc.jam:2: in load
rule Copyright unknown in module adoc.
[path-to-boost]\tools\build\src/kernel\modules.jam:295: in import

The problem is that it does not seems to have any error, but there is also nothing else (no folder created, no files, nothing). I tried to change a few things (run the 'install' command separately for example), but I always get this output and nothing more, so I wonder if I miss something, and what to do next.
What you see is actually the error message. Apparently, there is something wrong with the comment style in adoc.jam. If you look at the file, you will see a ranged comment using the style
#|
Copyright...
|#
which is not recognized properly. Thus, line 2 contains an invalid statement.
If you add a # at the beginning of each comment line, bjam will process the file and you will see the next file containing the same error. I had to edit 7 files until I ran into a different type of error.
