Hi Michael,

Those instructions are for the GHC head. For 7.10 and earlier this page https://ghc.haskell.org/trac/ghc/wiki/Building/GettingTheSources/Legacy should have been updated but it seems it never was..

To get the tarballs on that version do git clone git://git.haskell.org/ghc-tarballs.git

I will update the legacy page later.

I'm trying to test a patch I wrote for Windows builds[1]. I'm following the preparation guide[2], but my configure step fails[3] with config.log contents[4]. Note that I'm building on the ghc-7.10 branch, not master. Is it possible that this would contribute to the unrecognized --enable-tarballs-autodownload option, and/or the inability to compile C files?
