I added the -mno-avx compiler flag after noticing some errors when trying to install in my Win7 environment. I don't know a lot about Advanced Vector Extensions, but I was able to track down the 'illegal instruction' errors well enough to find that they had something to do with AVX. Adding the -mno-avx flag allowed me to install the package. I think the worst downside of including this compiler flag might be sub-optimal performance. |

I noticed a Stack Overflow user saying that this fork by fixes the Windows 8 installation bug. I was hoping @cpeeples might see this tag and be able to explain what the changes to Makevars.win are doing. Do they fix the versions of Windows that don't work? Is there any reason to think they might break the versions of Windows that are already working? Unfortunately I can't test on Windows myself.
