Arch Linux

this is no real bug report as the package works. but as building the apple swift package fails with this error i'd be interested if you have a quick idea what it could be, that compiler-rt cannot be built with clang++.


$ export CC=clang
$ export CC=clang
$ makepkg -s

and it really gives the same error when compiling swift.
