"recent libcxx regression" reason discovered. clang version info/folder changed. possibly accidental?

[Stellard, Thomas]

Hi,

I just submitted a patch which adds a symlink on both the automake and cmake build systems, can you test and review?

Thanks,
Tom

Thanks for raising this issue.  I think we should be able to add
a symlink from major.minor to major.minor.patch.  I will work on a patch
for this.
