Answering my own question:
When I build cross compiler using FpcUpDeluxe, where I set "Cross Build
Options Override" to "-Cparmv7A" (The Cortex -A9 cores implement the
ARMv7-A architecture) then I can sucessfully compile my application for
Drawback is that I must now maintain 2 FPC installations/cross-compilers
(Win32-WinCE): one for targer WinCE 5,6 with CPUs ARMv5 and another for
WinCE 7 with ARMv7 CPU (It is not sufficient to setup build modes in
project ... also all units must be pre-compiled ... at least I do not
know how to bypass this limitation)
