If you don't want philosohic stuff read the end of the mail :-) for my 
conclusions to go for now ...

Release 28-pre10 does not include this anymore. Here the codefragment:

/***************************** INCLUDES *****************************/

/* Do not put any header in this file, this creates a mess when

 * relevant headers anyway... Jean II */
/*#include <linux/types.h>*/        /* for "caddr_t" et al      */
/*#include <linux/socket.h>*/       /* for "struct sockaddr" et al  */
/*#include <linux/if.h>*/       /* for IFNAMSIZ and co... */

Sorry. What do you mean with that?
hostapd/wpa_supplicant is dual license GPL version 2 and BSD,
iwlib.h is realeased unter GPL license.

Is this a problem because not BSD license or what do you mean?
sample_pm.c in wireless_tools is realease under LGPL, MPL or BSD license.

If this is a problem we could see with Jean or did you do that already 
some time ago?

Ok this seems to be the problem. I do not know the bsd license but would 
it help if Jean would change the
license to dual license of gpl and bsd of only the header file?

Ok  forgott everything above ...
Only philosophic questions.

I have no compile both with you wireless_copy.h and my madwifi patches 
NOT iwlib patches and
my madwifi patches.
With this I was able to compile wpa_supplicant and hostapd.
With new version of wireless.h of Release 28-pre10 copyied to 
wireless_copy.h I was not able to compile.

Not much. An include file more or so as sent already but the fact is to 
have a version which people can use
to compile the whole stuff without applying here a patch there a patch ...


Ok here my conclusions:

I send here all patches for madwifi-ng and wpa_supplicant-0.4.6 and 
hostapd-0.4.6 together.
With this patches it is possible to compile a working 
wpa_supplicant/hostapd for madwifi-ng release 1314.

But as noted before with this patches it works fine at least for me :-)
