+# IMPORTANT NOTE:
+# This script no longer accepts an optional argument.
+# It was removed by the same person who added it -- me, drobbins -- when I optimized
+# bootstrap to complete 20 mins to 2 hours faster, depending on CPU. I did this by 
+# merging both stages of bootstrap into a single stage. We no longer compile gcc and
+# binutils twice. Doing this is unnecessary and a holdover from very early versions
+# of Gentoo, where we were being ultra-paranoid.

+# 2.14.90.0.6 build for i486, and bootstrap then merge 2.14.90.0.7 for i686,
+# we will not have issues.  More below ...), gcc's search path will
+# still have
+#
+#   /usr/lib/gcc-lib/i486-pc-linux-gnu/<gcc_version>/../../../../i486-pc-linux-gnu/bin/
+#
+# before /usr/bin, and thus it will use the i486 versions of binutils binaries
+# which causes issues.  The reason for this issues is that when bootstrap merge
+# exactly the same version for i686, both will have installed the same files to
+# /usr/lib, and thus also USE the same libraries, cause as/ld to fail with
+# unresolved symbols during compiling/linking.
