Getting Started on Windows Documentation - Does bootstrap.bat Need the Toolchain as an Argument?

[stellarpower@…]

Hello,

I am trying to build boost on Windows using mingw32 (as setup by Qt5). I was following the instructions as per http://www.boost.org/doc/libs/1_58_0/more/getting_started/windows.html#id37 . I extracted the sources, went into /tools/build and ran

bootstrap.bat
Bootstrapping the build engine
'cl' is not recognized as an internal or external command,
operable program or batch file.

Failed to bootstrap the build engine
Please consult bootstrap.log for furter diagnostics.

Further research online suggested I should have used

bootstrap.bat mingw

after which the bootstrap completes successfully. If this is the case, please could the documentation be changed to state this?

Thanks
