I had very similar problems when trying to install the current development
version on cygwin (the package python3-3.10.2 failed to build). I was able
to fix this by manually specifying in the configuration that the system
python3.8 should be used (python3.9 failed for separate reasons), but then
))

I agree, the best is to speed up matrices at all, instead of creating a
dangerous hack, just to speed up 2x2 Matrices.
Further I think it's natural to inherit (most) matrix classes from
Matrix, so this should not be changed.

but it should be
\left(\begin{array}{r}
\frac{-a - 1}{b}

or
\left(\begin{array}{r}
\frac{-(a + 1)}{b}
\end{array}\right)
