* Removed '--no-warn-mismatch' option from Makefile. This option
makes 'ld' to overlook binary objects compatibility. * Moved $(PLATFORM_LIBS) from the library group (--start-group ... --end-group) outside of the group. This will make 'ld' to do _multiple_ search in the library group when resolving symbol references and do only a _single_ seach in libgcc.a after the group search. * Fix stability problems on CPC45 board again. * Make image detection for diskboot / usbboot / scsiboot more robust (also check header checksum)
