  1. Packages with undeclared dependencies:
  1. Packages where rebuilding with a later version causes a DLL name to change, breaking another package:
  1. Packages that interfere with the building of another package:
  • libusb-compat provides usb.h, causing a name collision with mingw-w64 which broke the build of usbview and any other software using native Windows USB headers
  1. Packages that cannot be installed at the same time:
  1. Packages that should have been rebuilt a long time ago to benefit from bugfixes
