 	Of course, but the examples should all be valid. This one 
 prevents make buildworld, so should be replaced by something that 
 doesn't.

 	Except that's provided already with the example of CFLAGS, so 
 would make sense iff CFLAGS had another example value.
 
 # CFLAGS controls the compiler settings used when compiling C code.
 # Note that optimization settings other than -O and -O2 are not recommended
 # or supported for compiling the world or the kernel - please revert any
 # nonstandard optimization settings to "-O" before submitting bug reports
 # without patches to the developers.
 # Note also that at this time the -O2 setting is known to expose bugs in
 # libalias(3), and possibly other parts of the system.
 #
 #CFLAGS= -O -pipe
 #
 # CXXFLAGS controls the compiler settings used when compiling C++ code.
 # Note that CXXFLAGS is initially set to the value of CFLAGS.  If you wish
 # to add to CXXFLAGS value, "+=" must be used rather than "=".  Using "="
 # alone will remove the often needed contents of CFLAGS from CXXFLAGS.
 #
 #CXXFLAGS+= -fmemoize-lookups -fsave-memoized
