If I may ask, what are you using symlinks for? (I want them to eventually reduce the space consumed by the prefix, but getting them upstream has been a challenge)
My usecase, admittedly probably pretty nontypical, is that I'm working on getting the libc++ testsuite for the C++17 std::filesystem module to work with MSVC's STL, as a preparatory step for trying to implement std::filesystem in libc++ for windows targets. (Previously, both libc++'s implementation and tests of this part were very much unix-only.) I'm not much of a windows user myself and mostly cross compile, so being able to do most of the testing with wine makes the work much more convenient.
So far, mostly everything exercised by the testsuite works the same in wine, but there's a bunch of tests for symlinks (some entirely disabled, and some that work on native windows but not on wine). I'm not sure if there's other issues on the wine side still, but these two issues are the ones that I've so far pinpointed on the wine side.
