Description Alessandro Barbieri 2019-09-25 00:39:39 UTC 
I have -Wimplicit-function-declaration in CFLAGS and CXXFLAGS
the following packages fail to configure (for now)

sys-devel/llvm
sys-devel/lld
sys-devel/clang
dev-util/lldb

-- Performing Test CXX_SUPPORTS_CXX_STD - Failed
CMake Error at cmake/modules/HandleLLVMOptions.cmake:462 (message):
  The host compiler does not support '-std=c++11'.
Call Stack (most recent call first):
  CMakeLists.txt:643 (include)


-- Configuring incomplete, errors occurred!

I'll only attach logs for llvm, the others have the same failures

It's fun stuff you're doing but if you're doing the kind of fun-breaking-stuff, you need to send fixes upstream yourself.
