Here is where compiling guile stops with cvs guile, morning of May 4th
(which contains your check).
Note: I do a cvs update on my Linux latop running Debian Potato, build
and install Guile there, then do a "make dist" and copy the .tar.gz to
the Cobalt box.

Just to make sure you understand, AF_INET6 *is* defined, but the
structures for aren't there.  There is a pointer to the structure, but
no size information.  The structures *are* defined in <linux/in.h>, but
so are a boatload of #define's that conflict with other .h files.   I
tried using #include <linux/in.h> and not #including others, but I
couldn't resolve the conflicts.

The structure that the compiler doesn't know the sizeof is sockaddr_in6.

I also tried  to build --disable-networking.  It compiles and builds
fine, but still core dumps.

No, I don't think so.
