+On Windows, do not use the mingw/msys environment from https://www.mingw.org as it will miscompile the OpenBLAS math library
 
 The recommended way to setup your environment follows:
 
 1. Download and extract mingw (e.g. x64-4.8.0-release-win32-seh-rev2.7z) to C:/MinGW (or similar location) from [Mingw64](https://sourceforge.net/projects/mingwbuilds/files/host-windows/releases/4.8.0/64-bit/threads-win32/seh/)
 2. Download and extract msys (e.g. msys+7za+wget+svn+git+mercurial+cvs-rev12.7z) to C:/MinGW/msys/1.0 (or similar location) from [Mingw64/Msys](https://sourceforge.net/projects/mingwbuilds/files/external-binary-packages/)
 3. Add the line "C:/MinGW /mingw" to C:/MinGW/msys/1.0/etc/fstab (create the file if it doesn't exist)
-4. Replace C:/MinGW/msys/1.0/bin/make.exe with a copy of make.exe extracted from [mingw-msys](https://sourceforge.net/projects/mingw/files/MSYS/Base/make/make-3.81-3/) (e.g. make-3.81-3-msys-1.0.13-bin.tar.lzma)
+4. You may need to replace C:/MinGW/msys/1.0/bin/make.exe with C:/MinGW/msys/1.0/bin/make-old.exe or with a copy of make.exe extracted from [mingw-msys](https://sourceforge.net/projects/mingw/files/MSYS/Base/make/make-3.81-3/) (e.g. make-3.81-3-msys-1.0.13-bin.tar.lzma) if the build does not start correctly
 
 These sections assume you are familiar with building code. If you are not, you should stop reading now and go the the section on binaries. Regardless of which set of steps you followed above, you are now ready to compile julia. Open a unix shell by launching C:/MinGW/msys/1.0/msys.bat (or your favorite shortcut to that file). 
 
 Run the following commands in your build directory ($HOME at C:/MinGW/msys/1.0/home/your_name is fine)
 1. `git clone https://github.com/JuliaLang/julia.git`
 2. `cd julia`
 3. `make`
-NEVER use the `-j` argument to make. Windows will sometimes corrupt your build files. Additionally, make will probably lock up several times during the process, using 100% cpu, but not show progress. The only solution appears to be to kill make from the Task Manager and rerunning make. It should pickup where it left off. Expect this to take a very long time (dozens of hours is not uncommon).

-Unfortunately, the version of gcc installed by Ubuntu is currently 4.6, which does not compile OpenBLAS correctly. So first we need to replace it.
