   In ACL5 (Win NT), it seems that the names of automatically created 
   functions by Defstruct are declared inline. Even with the following 
   compiler settings:
     (proclaim '(optimize (speed 0) (safety 3) (space 0) (debug 3)))
   
   Does someone know how to control this?

I haven't tested, but I suspect declare/declaim notinline will have
the desired effect.  That's the only _portable_ way to control
function inlining.
