libsocket is not near that goal yet. No code exists to support S_IFSOCK or
S_ISSOCK(). I hope to add stat() support for sockets sometime.

I'm confused what you mean about 'mknode' (mknod() in
libc/compat/sys/stat/mknod.c?). I'm sorry, but I have heard the term
"degenerate" only in a Physics/Chemistry context, and I'm not sure what
you mean here.

I agree that just #define'ing S_IFSOCK is too simplistic and will break
things (hence my concern about autoconf scripts).

So this seems the like the best solution given that the support isn't
in libsocket yet. I suggest lsck/stat.h, but the name isn't important.

Bye,
