Subject: PROBLEM: Aironet compile failure 2.6-test9/Alpha architecture

  Aironet is not listed as i can find in the file MAINTAINERS, however, 
This report needs to go somewhere and do something. The maintainer is 
however listed in airo.c. merry carbon-copy, people.

Quite simply, the compile fails with the following error.   I'm not sure 
anyone else  is using an aironet card under Alpha, so I guess someone 
needs to report this.
I must say Aironet can be a real pain.

This is blocking me from further testing of 2.6-test9 on alpha.  (I'll 
test more hardware if someone wants ot kick down a magma PCI breakout, 
as my machhine is full, and literally buried in it's own hardware)
 I'm willing to bet the problem is some 64 bit cleanliness issue.. I 
don't really code (but for pidgin FORTRAN, and i'd likely get killed for 
sending a patch in fortran)
There is a possibility this may be caused by GCC bug PR-9164, which is 
present in debian 3.0  Alpha (Debian people: READ: *fix it*)  which I am 
running.    

  Hope this is fixable.
