Version 0.9.2 of tecomp has been released.
That version is functionally equivalent to 0.9.1 and 0.9.
However it is now possible to generate tecomp binaries on windows which work without the cygwin.dll. I.e. in order to compile tecomp, cygwin is needed. But the compiled binaries gen_dir/bin/tecomp.exe and gen_dir/bin/atecomp.exe can be copied to any other Windows machine which does not have a cygwin installation.
For details see the README.
