+Link assembler softfloat functions into gcc. As the functions are there
+in that case anyway, don't add switches for float lib.

+Upstream will not fix this because oabi is dead.

+This trivial patch causes gcc to emit a warning whenever it generates a
+trampoline. These are otherwise hard to locate. It is rigged to default
+ON - to have it default to OFF remove the text 'Init(1)' from the

+Hi,
+
+The attached patch makes sure that we create smaller object code for
+simple switch statements. We just make sure to flatten the switch
+statement into an if-else chain, basically.
+
+This fixes a size-regression as compared to gcc-3.4, as can be seen
+below.
+
+2007-04-15  Bernhard Fischer  <..>
+
+	* stmt.c (expand_case): Do not create a complex binary tree when
+	optimizing for size but rather use the simple ordered list.
+	(emit_case_nodes): do not emit jumps to the default_label when
+	optimizing for size.
+
+Not regtested so far.
+Comments?
+
+Attached is the test switch.c mentioned below.

+Subject: [PATCH] Fix: libjava cross build issue
+
+Taken from upstream r163580:
+
+Fix building ecjx in cross compile mode.
+
+libjava/:
+	PR libgcj/40868
+	* configure.ac: Add GCC_FOR_ECJX variable.  Ensure
+	GCJ_FOR_ECJX is always set.
+	* Makefile.am [!NATIVE] (ecjx.$(OBJEXT)): New rule.
+	* Makefile.in: Regenerate.
+	* configure: Regenerate.
+	* gcj/Makefile.in: Regenerate.
+	* include/Makefile.in: Regenerate.
+	* testsuite/Makefile.in: Regenerate.
+
+This is a fix for:
+Bug 40868 - ecjx.cc should be compiled by host gcc
