#21 opendir() failed (mingw-runtime-0.4-20001204)

Now it works back with mingw-runtime-0.4.tar.gz !

Hi, no it's no more an issue, it only failed with mingw-
runtime-0.4-20001204, I never understood why.
So you can consider this case closed!

[Keith Marshall]

Although closed, it may be worth noting that the dirent.c module, (which provides opendir() and friends), has been completely reworked for WSL; the reworked version is not ABI compatible with the old.

[Earnie Boyd]

We should note this in the Release Notes and we'll need to release a new GCC/binutils set at the same time.
