-#   You might try to:

-#   - run "make V=1", which displays the full commands invoked by make,
-#     to further investigate the problem
+# It can help to run "make bootstrap", which can resolve many build
+# failures caused by incrementally building from a previously built
+# checkout.

+# Failing that, running "make V=1" will cause Make to display the full

-#   You might try to:
-#   - run "git clean -fdx" and run "make bootstrap" again, which might
-#     fix the problem
-#     !BEWARE! "git clean -fdx" deletes all files that are not under
-#     !BEWARE! version control, which means that all changes to such
-#     !BEWARE! files will be lost and cannot be restored later
-#   - run "make V=1", which displays the full commands invoked by make,
-#     to further investigate the problem
+# If "make bootstrap" failed, try running "make extraclean" and then
+# "make bootstrap" again.  If that still fails and you are building
+# Emacs from a repository checkout, run "git clean -fdx" and retry
+# "make bootstrap".  Otherwise, please report a bug by sending email
+# to bug-gnu-emacs@gnu.org.
