I'm not sure who's not so smart - users of Scheme, MIT, or passive windows lusers like yours truely.
While
poking around at the MIT open source courses for computer science, I
snagged MIT / GNU Scheme for windows. Built with an obscure and
possibly irrelevant C++ compiler toolchain for windows, it also manages
to somehow redistribute parts of cygwin dll files. This is the worst
possible outcome of free software for windows from a philosophy
standpoint - a gnu project built for windows without using
MinGW, that has to redistribute parts of cygwin along with the binaries as well.
I could punch myself several times over; I haven't been this mad since I uncovered my
gnu arch issues.
