Hi Russell,
Unfortunately the batch file build on Windows was maintained by Jason
Moxham who sadly passed away in 2012. In consequence it had not been
maintained since then and could not therefore be used to build MPIR 2.7.0.
I am puzzled by the problems you have (or foresee) with vsyasm. It
should be no more difficult to use vsyasm with Visual Studio than it is
to use yasm. All you have to do for Visual Studio 2015 is to add
vsyasm.exe to the Visual C++ binary directory at:
C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin
after which the Visual Studio builds should work 'out of the box'.
There was a problem with the vsyasm.exe provided on the yasm site but I
believe that Peter Johnson has now solved this. If it still fails, I
will be happy to send you a version that I know works.
Since you have to put yasm somewhere where Visual Studio can find it,
how is doing this for vsyasm any different?
Can you explain in what way the current Visual Studio builds are not
repeatable?
Maybe I can help you to set up an environment in which these builds will
work for you.

This could be done but it would need a volunteer to update them for MPIR
2.7.0 and then to maintain them for the future.
best regards
