Roland thanks.

Can one of the Savannah project members please create a task for this?  
I tried to but apparently only members can create new tasks, etc?

Also, does anyone happen to know why i386_fp_save and i386_fp_regs are 
split out?  In Linux's user.h they are in 1 struct: user_i387_struct.


Thanks as always!
