What's the meaning of $@?

I came across the makefile when I read something about flex

  fb3-1: fb3-1.l fb3-1.y fb3-1.h
     bison -d fb3-1.y
     flex -ofb3-1.lex.c fb3-1.l
     cc -o $@ fb3-1.tab.c fb3-1.lex.c fb3-1funcs.c

but what's the meaning of $@? Is it in the shell or some argument of gcc?

$@ is just short-hand for the file name of the current target (fb3-1 in this case).

See the Automatic Variables section of the gnu make manual for full details on this and other useful automatic variables such as $<.
