When I taught programming (I started teaching 22 years ago), the course was still having students either use GCC with their university shell accounts, or if they were Windows people, they would use Borland C++ we could provide under some kind of fair use arrangement IIANM, and that worked within a command shell on Windows.
On the other hand, with tcc, you'd know exactly what you were dealing with.
I used it just the other day to do some tests. No dependencies, no fiddling around with libwhater-1.0.dll or stuff like that when on Windows and so on.
