* added undefined label detection in internal assembler, this prevents
a lot of ld crashes and wrong .o files
* .o files aren't written anymore if errors have occured
* inlining of assembler labels is now correct
(tos contains all target_infos and
we use CPU86 and CPU68 conditionnals to
get the source operating system
this only works if you do not undefine
the source target !!)
* several cg68k memory leaks fixed
+ started to change the code so that it should be possible to have
a complete compiler (both for m68k and i386 !!)
