Windows: Don't get pointers to C strings while vector is still unstable. * src/main-cli.cc, src/main-gui.cc, src/main.in.cc, src/octave-config.in.cc, src/octave-svgconvert.cc: The memory used by a vector is not guaranteed to be stable when elements are added with push_back. Wait until vector is complete before getting the pointers to the corresponding C strings.
