Created attachment 893036 [details] emerge log Compiling mdadm for ChromeOS, using clang instead of gcc, emerging 4.2 and 4.3 fails with: ``` * ERROR: sys-fs/mdadm-4.3::portage-stable failed (compile phase): * Bad gcc [-Q --help=warnings] invocation ``` The issue has been introduced in mdadm with commit 8268821b434d ("mdadm: Add Wimplicit-fallthrough=0 in Makefile") added to mdadm-4.1. It can be fixed by using `$(CXX)` instead of `gcc` directly.
