\Consider a symbol table that is used to store strings. You could

\		struct SYMTAB *sym_next;
\		int     sym_type;
\		char    *sym_text;
\	} SYMTAB;
\
\This has the drawback that one needs two allocates for the
\structure [...]

symtabptr = (SYMTAB *) malloc(sizeof(SYMTAB) + strlen(text) + 1);
symtabptr->sym_text = (char *) symtabptr + sizeof(SYMTAB);
strcpy(symtabptr->sym_text, text);
