-dnl set DEBUG/RELEASE flags to default-values if unset
-
-dnl - Do not use -dDEBUG because this will enable range-checks that will fail with USDX.
-dnl - Disable -Xs which is defined in fpc.cfg (TODO: is this necessary?).
-dnl - For FPC we have to use DEBUG_MODE instead of DEBUG to enable the apps debug-mode
-dnl because DEBUG enables some additional compiler-flags in fpc.cfg too
