* compiler.h
added member cType to struct VAR
* harbour.y
added { iVarScope = VS_MEMVAR; } to PRIVATE, PUBLIC, and PARAMETERS statements to avoid errounous error:
"declaration follows executable statement"
added: AliasExp '=' Expression Crlf { /* TODO */ GenPCode1( _POP ); }
to statement definition to avoid parse error on M->Var = "Value" statments.
the _POP will balance the stack but the assignment is not implemented yet.
changed --iLine to iLine in yyerror() to correct errornous line numbers in parase error messages.
added check for null pointer on few references to pVars->szName
* hbpp.c, hbpmain.c, hbpint.c
prefixed messages in all printf() with \n and postfixed with \n until modification to GenWarning() and GenError()
