-I/usr/local/src/linux/v2.2.7 ayuda en estos casos.  El programa va a
incluir <asm/foo/bar/baz.h>; si utilizar -I para decirle donde encontrar las
cabeceras, se arregla tu problema.

        Well, this kinda belongs to the can of worms we fondly
 remember as "Debian's /usr/src policy" ;-). Lets see if I can address
 this. Firstly, kernel headers are not merely for libc6
 compilation. In fact, /usr/src/linux is not referenced at all by
 normal compilation processes: those depend, in particular, on the
 symbolic link /usr/src/linux-2.0.32, which is provided by either
 kernel-headers-2.0.32 or by kernel-source-2.0.32.

 /usr/src/linux           is meant to be a link to the chronologically
                          latest installed set of kernel headers
 /usr/src/linux-X.X.XX    is meant to be a link to a specific version
                          of kernel include files.

        Then that means you could not have more than one kernel
 headers or source packages installed. I have, at the moment, 2
 header packages and 4 source packages on my machine. If they all
 tried to go into /usr/src/linux; that would be chaos. Espescially if
 /usr/src/linux were merely overlaid with the most recent install
 (imagine installing 2.0.34 over 2.1.82 -- what a mess)
