https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: games-fps/quakeforge-0.7.2_p20210722 fails to compile with -fno-common. Discovered on: amd64 (internal ref: lto_tinderbox) NOTE: This machine uses lto with CFLAGS=-flto -Werror=odr -Werror=lto-type-mismatch -Werror=strict-aliasing To reproduce this issue you may want to set CFLAGS="${CFLAGS} -fno-common" or compile it with gcc-10 that enables -fno-common by default.
