/************************** MULTICALL HACK **************************/
/*
 * The idea for multicall is to put all the tools and the library in
 * the same binary. This way, you can save the overhead of the library,
 * of each tool, can better optimise the code and throw away the stuff
 * you don't need from the library.
 * This almost divide the size of the tools by two (without stripping).
 * On the down side, you no longer have the libiw for other tools to
 * use, but for the target systems (embedded), this doesn't matter
 * much, as they just need to configure the card...
 * Note that splitting the lib and the multicall tools would not
 * make sense, as most gains are found in the inclusion of the lib...
 *
 * Our strategy is to include directly the *.c, rather than compile
 * them separatly. This allow to simplify compilation and hide the
 * multicall tweaks from the other tools.
 * Yeah, this leads to a bit a preprocessor abuse...
 * Jean II
