about possibly-questionable C code. This is intended for developers
and is useful with GNU-compatible compilers. On a recent GNU system
there should be no warnings; on older and on non-GNU systems the
-generated warnings may still be useful.
+generated warnings may still be useful, though you may prefer building
+with 'make WERROR_CFLAGS=' so that the warnings are not treated as
+errors.
-Use --enable-silent-rules to cause 'make' to chatter less. This is
-helpful when combined with options like --enable-gcc-warnings that
-generate long shell-command lines. 'make V=0' also suppresses the
-chatter.
+Use --disable-silent-rules to cause 'make' to give more details about
+the commands it executes. This can be helpful when debugging a build
+that goes awry. 'make V=1' also enables the extra chatter.
Use --enable-link-time-optimization to enable link-time optimizer. If
you're using GNU compiler, this feature is supported since version 4.5.0.
