--- Comment #41 from Robin Bankhead <kde.b...@headbank.co.uk> ---
If you are talking C*FLAGS obviously being Gentoo we users set these
personally, mine are (for all *FLAGS)
-march=native -O2 -pipe -fomit-frame-pointer
While looking in the build log I also noted some warnings in what I take to be
keymapping-related code, sharing below in case relevant:
XKBMAlloc.c: In function 'SrvXkbChangeKeycodeRange':
