Thanks, I believe I already do use -XR, here is entire compilation line:
/opt/cross/br/arm/armv7a/6.2.0.v6/usr/lib/fpc/3.2.0/ppcrossarm -O3 -CX -XX -Xs
-veibq -vw-n-h- -MDelphiUnicode -Sg -Sc

-o./build/arm-linux/bin/mkCGGTTS
./src/mkCGGTTS.pas
and still I get all those warnings. Something's wrong with my command-line
options?
Thanks,
