+# Recently there has been a lot of stability problem in Gentoo-land.  Many
+# things can be the cause to this, but I believe that it is due to gcc3
+# still having issues with optimizations, or with it not filtering bad
+# combinations (protecting the user maybe from himeself) yet.
+#
+# This can clearly be seen in large builds like glibc, where too aggressive
+# CFLAGS cause the tests to fail miserbly.
+#
+# Quote from Nick Jones <carpaski@gentoo.org>, who in my opinion
+# knows what he is talking about:
+#
+#   People really shouldn't force code-specific options on... It's a
+#   bad idea. The -march options aren't just to look pretty. They enable
+#   options that are sensible (and include sse,mmx,3dnow when apropriate).
+#
+# The next command strips CFLAGS and CXXFLAGS from nearly all flags.  If
+# you do not like it, comment it, but do not bugreport if you run into
+# problems.
