3. Dependencies are not made when using Windows versions of the GCC on a POSIX
platform (i.e., Cygwin). This is because the dependencies are generated
using Windows paths which do not work with the Cygwin make.

If you are building natively on Windows, then no such conflict exists
and the best selection is:

mkwindeps.sh is a version that creates dependencies using the Windows
native toolchain. That generates Windows native paths in the dependency
file. But the mkwindeps.sh uses cnvwindeps.c to convert the Windows

generation but is generally th best option available for that mixed
