As stated in the previous mail, I actually use the "m52235evb-rom.ld" linker
script .
The "m52235evb-rom.ld" refere to the startup code named "cf-unhosted-crt0.o".
Here is the first lines of that file:

				   ----------

STARTUP(cf-unhosted-crt0.o)
OUTPUT_ARCH(m68k)
ENTRY(__start)
SEARCH_DIR(.)
GROUP(-lc -lunhosted -lcf)
__DYNAMIC  =  0;

				   ----------

Refering the the above text, we can also see that one of the library is
named "unhosted", so I suppose that all is ok here too.

So, all seems to be Ok (no use of hosted things).

Is it possible that the "cf-unhosted-crt0.o" is not the startup code
for the unhosted target !?


Is the source code of "cf-unhosted-crt0.o" is available, so I can
modify it, and get rid of that problem ?
