And me having a Gtk-rs project that takes 18 minutes to compile from scratch with an empty frame and a couple of menu entries on a Core Duo.

My test project to validate compile time improvements on each Rust release.

The C++ original with Gtkmm takes less than 10 minutes.

Really miss Delphi like compile times, so then I just end up doing something on Qt, Lazarus or Eiffel Community instead.
