Dependency upon itself is curious, but other than that, this is a normal situation for a package manager. Some packages are split for easier maintenance of each, but are interlocked in their typical usage pattern. > And also we have some dependency omissions.

While this is "not good", this is also not particularly bad for packages in base - this group is always installed. > Is this a known issue or should I report in more detail? Nonetheless, such issues are best kept highlighted, unless it is clearly seen/documented as intended. -- With best regards, Andrey Repin Saturday, September 30, 2017 11:54:56 Sorry for my terrible english... -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
