The --with-tcp configure flag enable building of tcp support into
a loadable module. However, you still need to load the module at
runtime to access the socket interface, just as you need to load
the CLX or ASDF modules at runtime to access them.

I think this is due to change in src/configure.in from 1.106 to 1.107
which removes the TCP variable definition. However, this is still 
needed in some files like symbols_list.h (and mayeb at other places),
otherwise symbols like SI::OPEN-CLIENT-STREAM are not defined.

Maciek, do you confirm?
