Thanks.
Decided to try with a batch file with some more cleanup etc [1].

With this I hit this problem compiling the test program:
Assembling test
test.pas(12,24) Warning: Object system.o not found, Linking may fail !
....(and so on for more .o files)
Error! E2008: cannot open system.o : No such file or directory
...(and so on)

I do notice a lot of .a files (system.a) etc in
C:\Development\fpctrunk\rtl\units\msdos but no DOS .o files there or
anywhere else....
