# 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.
