The full error message includes a pointer to the command that was
not recognized:

set surface explicit
                   ^
"3dtest.gp", line 13: ';' expected

Apparently that command is more recent than version 4.6.
It was introduced to solve exactly the problem you are having, 
"only connect lines into a surface if the command explicitly says
to plot with surface".

I think  the best option is to update to gnuplot version 5.    
I do not recall if there was a work-around in earlier versions.
Maybe someone else remembers.
