Hello everybody,
I am building grep 3.12 in a clean build environment for Arch Linux. That
fails when building with link time optimization is enabled:

lto1: all warnings being treated as errors
The build succeed as soon as I disable link time optimization. Would be nice
to have a fix for this to reenable lto. Let me know if I can provide more
information on this. Thanks!
