Comment (by Phyx-):

 Yes, though this advice of prefering the mingw packages over the msys ones
 doesn't just apply for `python`. I've amended the section at
 https://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/Windows#ConfiguringMinGWproperly

 The way I always do it is to make sure in my profile that `/mingw64/bin`
 is the first thing on the `$PATH`. I need to make some time to re-evaluate
 that page, as I am not sure we need any of those msys versions of the
 tools we're telling people to install.

 They've bitten us quite a few times already.
