[VLAN] "strange" compilation of vconfig with gcc

[carlos at fisica.ufpr.br (Carlos Carvalho)]

I compiled vconfig with gcc 4.1 and it produced a large binary,
which also depends on the c++ libs. I removed the // comments and gcc
produced a much smaller binary that doesn't need the c++ libs! I think
this is strange, particularly because the // comments are in c99 and
have nothing to do with c++...
