This -warn-error flag invariably gets into release tarballs and breaks builds on distributions that run tests as a part of release process. The OCaml binding tests are especially critical, since they often expose lingering toolchain bugs, and so it is replaced with -w +A (equivalent to -Wall). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@242550 91177308-0d34-0410-b5e6-96231b3b80d8
