No, with debian gcc, /usr/lib/gcc-lib/i486-linux/3.3.5/include/asm/ is
a real directory that includes nothing but posix_types.h.

Looks like you're right. On Debian, "make C=1 V=1" ends up with:
sparse -D__linux__ -Dlinux -D__STDC__ -Dunix -D__unix__ -nostdinc
-isystem /usr/lib/gcc-lib/i486-linux/3.3.5/include -D__i386__
-Wp,-MD,init/.main.o.d -nostdinc -isystem
/usr/lib/gcc-lib/i486-linux/3.3.5/include -D__KERNEL__ -Iinclude -Wall
-Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common
-ffreestanding -O2 -fomit-frame-pointer -pipe -msoft-float
-mpreferred-stack-boundary=2 -march=i686 -mregparm=3
-Iinclude/asm-i386/mach-default -DKBUILD_BASENAME=main
-DKBUILD_MODNAME=main init/main.c ;

so sparse is picking up the posix_types.h from the -isystem path
instead of the -I path as it should.
