  #
  # We assume GNU make as the `make` command as we use GNU make extension
  # aggressively in man/Makefile and win32/Makefile.
  #
  # man/Makefile is used to generate man files only when rst2man is installed.
  # win32/Makefile is used only when either source.mk or win32/*.in is updated.
  # In other cases we can still build ctags without GNU make.
  #
  # The following tests use bmake (NetBSD make) to check if GNU make extensions
  # are not used unintentionally.
  #
  # On Fedora 31 bmake package cannot be installed because a package required by
  # bmake is not available. More inspection is needed. Fedora 30 is the last
  # version where bmake can be installed.
