collect.c doesn't deal correctly with extended symbols in COFF object
files, e.g., the output from 'gcc -g' or 'g++ -g0'.

The loop:

	for (symindex = 0; symindex < symbols; symindex++ ) {

	  SYMENT symbol;
	  char *symbol_name;
	  extern char *ldgetname();
	  
	  ldtbread(ldptr, symindex, &symbol);
		...
	}

should instead look like this:

	symindex = 0;
	while (symindex < symbols) {

	  SYMENT symbol;
	  char *symbol_name;
	  extern char *ldgetname();
	  
	  ldtbread(ldptr, symindex, &symbol);
		...
	  symindex += 1 + symbol.n_numaux;
	}

so that "auxiliary" symbol table entries will be skipped.
This is necessary because ldgetname can core-dump on an auxiliary entry.
