2388 after "foo<char *>" and before "goo". Then lookup_partial_symbol
2389 will start looking at strings beginning with "goo", and will never
2390 see the correct match of "foo<char *>".
2392 Parenthesis example:
2394 In practice, this is less like to be an issue, but I'll give it a
2395 shot. Let's assume that '$' is a legitimate character to occur in
2396 symbols. (Which may well even be the case on some systems.) Then
2397 say that the partial symbol table contains "foo$" and "foo(int)".
2398 strcmp will put them in this order, since '$' < '('. Now, if the
2399 user searches for "foo", then strcmp will sort "foo" before "foo$".
2400 Then lookup_partial_symbol will notice that strcmp_iw("foo$",
2401 "foo") is false, so it won't proceed to the actual match of
2402 "foo(int)" with "foo". */
