 * External Libraries Customization
 *
 * This is the place where we do some slightly crappy libraries customization.
 * We are not proud of this, but at least, we try to avoid patching them in
 * place.
 *
 * In an ideal world, this file would not be needed, because external libraries
 * would not have bugs, their APIS would be done in a way that we could use them
 * as is, and their distribution process would make sure that they are properly
 * configured.  However, we do not live in such a world, so this file is
 * necessary.
