This is not a Cygwin problem.  Linux, for example, behaves the same.

What you did was create a symbolic link in Projects to the file
named Repos/bugn, a relative path name.  Any reference to
Projects/bugn is resolved to Projects/Repos/bugn.  This is correct,
but not what you intended.

One alternative would be

    $ ln -s ../Repos/bugn/ Projects/

Another would be

    $ ln -s $PWD/Repos/bugn/ Projects/

Which one is better depends on your environment and on what you're
trying to achieve.

Regards,
Gary
