+ lexlevel cleanup
normal_function_level main_program_level and unit_init_level defined
* tins_cache grown to A_EMMS (gave range check error in asm readers)
(test added in code !)
* -Un option was wrong
* _FAIL and _SELF only keyword inside
constructors and methods respectively
=> never use p^.loc.location:=p^.left^.loc.location;
+ finally I added now by default
that ra386dir translates global and unit symbols
+ added a first field in tsymtable and
a nextsym field in tsym
