problems with 0.0.4 and gcc-3.2/3.3

I've been working on 0.0.4 for a few days now and have encountered 
problems compiling hostap with gcc 3.2 and 3.3.  When i use 2.95 
everything works as expected.
I had thought 3.2 was working fine until fairly recently.

The system is debian sid/unstable on i386 with kernel 2.4.21-pre3.  

3.2 compiles cleanly and loads without errors and intitalizes the card, 
then immediately locks the system.  

3.3 shows the attached errors when compiling.  
when the module loads, the kernel panics and the system becomes unstable.

any ideas?
