The R language has some hacks specifically for mingw-w64 that
were caused by our handling of NaNs in sqrt(x). R uses a
special valued NaN to mean 'Not Available' and expects it to
be retained through various calculations. Our sqrt(x) doesn't
do this, instead it normalises such a NaN (retaining sign
Here's the sqrt(x) NaN propgation patch again, this
time with a reference to the IEEE standard and as
a git patch.
If it's ok to commit, can someone go ahead?

MSYS2 is still very actively maintained. You can download it from
https://msys2.github.io/ instead of SourceForge.
