Yann, all,

to my knowledge there's no such option in MacOS's ld.
There is - however - a libstdc++_static.a present on MacOS.
Only reading the caveats in Apple's documentation gives me headaches and
I'd refrain from trying anything of this stuff unless there's a
very good reason to do so.

It escapes me now why you would want to link statically (to libstdc++)?
What was the reason?
