+# Configure fragment invoked in the common section for subdirs
+# wanting multilib support.
+#
+# The common section was chosen because xiberty clobbers $srcdir in the
+# common section of its configure.in.
+#
+# The intent is to keep as much of this in one place as possible (and out
+# of each subdirectory, eg: newlib, libio, etc.) until the right way to do
+# this (ha ha) is decided upon.
+#
+# This is where a target selects what multilib directories to build.
+# It is advisable to support a few --enable/--disable options to let the
+# user select which libraries s/he really wants.
+#
+# FIXME: Multilib is currently disabled by default for everything other than
+# newlib.  It is up to each target to turn on multilib support for the other
+# libraries as desired.
+#
+# FIXME: It would be better if we could use the --print-multi-lib switch to
+# gcc to get the list of directories to build, but at this point the compiler
+# has not been built.
+
+# Only do this if --enable-multilib.
+# And only if at the top level, not a multilib subdirectory.
