In that case, we have got to change `-exxx` to `-e xxx`, and `-export-dynamic`

GCC compatibility certainly matters a lot, but I feel that some of my previous

I have never seen such usage before. You're supposed to use ```-rdynamic```.

I think ld `--export-dynamic` is exclusively caused by `-Wl,--export-dynamic`
or `-rdynamic`.
Do you have any example of `gcc -export-dynamic` uses?
