Committed with that name.

In your original patch, this hunk in pg_config_manual.h:

+ * You can define these by editing pg_config_manual.h but it's usually

+ *
+ *     ./configure --enable-debug --enable-cassert CFLAGS="-DUSE_VALGRIND"
+ *
+ * The flags are persisted in Makefile.global so they will be correctly

I don't think that necessarily works for all settings.  Maybe we should 
make a pass through it and ensure it all works sensibly, but that seems 
like a separate project.
