I had just commented out that declaration.  Modern (f)lex output will have an "#include <stdlib.h>" in the C output.


But there's another fix needed on around line 85

 *** 82,88 ****
  		      StackName [StackInd] = malloc (yyleng + 1);
  		      if (StackName [StackInd] == NULL)
  		        {
! 		          printf ("Line %d : memory allocation failed\n");
  		          return 1;
  		        }
  		      strcpy (StackName [StackInd], yytext);

The thing really needs a main() wrapper that does argument handling instead of that shell script to handle arguments.
