+2004-06-01 Paolo Bonzini <bonzini@gnu.org>
+
+ * Makefile.tpl (all.normal): Rename to all.
+ (all): Replace with a rule to pick the default
+ target from configure.
+ (all-gcc, configure-gcc): Use conditionals to
+ do nothing when toplevel bootstrap is going on.
+ (GCC directory bootstrap) [gcc-bootstrap]: Disable.
+ (Toplevel bootstrap) [gcc-no-bootstrap]: Disable.
+ * configure.in: Support --enable-bootstrap.
+
+ * Makefile.def: Remove new- prefix from toplevel
+ bootstrap targets.
+ * Makefile.tpl: Likewise.
+
+ * Makefile.def: Add bootstrap_stage 4. Add bootstrap2
+ target.
+
+ * Makefile.tpl (Toplevel bootstrap): Pass $(BASE_FLAGS_TO_PASS)
+ $(RECURSE_FLAGS) to recursive invocation of make.
+
+ * Makefile.in: Regenerate.
+ * configure: Regenerate.
+
2004-05-27 Daniel Jacobowitz <dan@debian.org>
* configure.in: Fix sed invocation for GFORTRAN_FOR_TARGET.
