I guess I found the cause. The problem is 2 fold:

1- The function GetProcessAffinityMask is not defined for WinCE, as it 
is not defined in fpc/rtl/wince/wininc/redef.inc (as opposed to 
fpc/rtl/win/wininc/redef.inc which includes GetProcessAffinityMask). 
Hence this function should be eliminated from utf8process.pp for WinCE.

2- Codetools are still pointing to the win version of redef.inc 
eventhough the project's LCLwidgetset is WinCE.
