+# NATDEPFILES must remain entirely on one line.  When building a cross
+# debugger, configure will cause this line to be commented out in the
+# Makefile.  Many non-GNU versions of make don't permit the use of a
+# continuation character (backslash) to extend a commented line.  As a
+# consequence, make considers subsequent tab-indented lines to be
+# some sort of error.
