+# We can't use automake's automatic dependency tracking, because it
+# breaks when using bootstrap-lean. Automatic dependency tracking
+# with GCC bootstrap will cause some of the objects to depend on
+# header files in prev-gcc/include, e.g., stddef.h and stdarg.h. When
+# using bootstrap-lean, prev-gcc is removed after each stage. When
+# running "make install", those header files will be gone, causing the
+# library to be rebuilt at install time. That may not succeed.
+
+# These manual dependencies do not include dependencies on unwind.h,
+# even though that is part of GCC, because where to find it depends on
+# whether we are being built as a host library or a target library.
