Steel Bank Common Lisp

       Hello,

I'm playing with sb-grovel and I'm curious about some compilation notes
that I get (I don't really mind getting them, but...):

the compilation tells me:

unable to optimize away %SAP-ALIEN: forced to do runtime allocation of
alien-value structure.

This occurs in a piece of code like this:

(with-winsize winsize ()
  blah blah)


with a grovel "constants" file as follows:

("sys/ioctl.h")

((:integer +tiocgwinsz+ "TIOCGWINSZ")
 (:structure winsize ("struct winsize"
		      ((unsigned 2) ws-row "unsigned short" "ws_row")
		      ((unsigned 2) ws-col "unsigned short" "ws_col")
		      ((unsigned 2) ws-xpixel "unsigned short" "ws_xpixel")
		      ((unsigned 2) ws-ypixel "unsigned short" "ws_ypixel"))))


So what's this note about ?

Thanks !


BTW, I see that sb-posix already contains termios stuff. Why not having
winsize and TIOCGWSZ / TIOCSWSZ as well ? Not that I'm suggesting to add
the whole world to sb-posix, but these 2 guys are related to each other...
