Yes. We ship project files for MSVC, and it's very easy to use them, even in a scripted install. Even I've built it with MSVC (for windows.sagemath.org). Given that you use Windows a lot, you should try it out :-) > We will certainly have the same naming convention between the linux > and windows builds in mpir-1.0.0.

How do you setup links like that on Windows? Somehow symlink support in windows is a bit different. > > Bill. > > 2009/3/1 Jeff Gilchrist <jeff.gilchr...@gmail.com>: >> >> On Sat, Feb 28, 2009 at 12:54 PM, <ja...@njkfrudils.plus.com> wrote: >> >>> This could make a nice "real world" benchmark for MPIR , where we have cache >>> misses and branch mispredictions.
