	# The following spinlock error should only bite if you compile without any -O in CFLAGS, so a tweak
	# shouldn't be necessary.  The solution is to add -O2.  According to Andreas Jaeger of SuSE, "glibc
	# *needs* to be compiled with optimization" (emphasis mine).  So let's fix the optimization settings,
	# not tweak glibc.
