Proposed
- Get Cygwin port working again. This depends on libSingular working. The Singular team would be very happy if this happened
- Take standalone applications and move them over to MinGW and/or MSVC if possible, i.e. the Salami tactic
- port pexpect to native Windows API - this is needed for MinGW/MSVC to work
- Once pexpect works we should combine the notebook, matplotlib-based plotting code, the calculus code and maxima to have a basic program useful to a lot of people
- port the remaining C/C++/Fortran code over to the new toolchain and get closer to a full working Sage
