3040 '(' as the first non-NULL character in terms of ordering. Like
3041 strcmp (and unlike strcmp_iw), it returns negative if STRING1 <
3042 STRING2, 0 if STRING2 = STRING2, and positive if STRING1 > STRING2
3043 according to that ordering.
3044
3045 If a list is sorted according to this function and if you want to
3046 find names in the list that match some fixed NAME according to
3047 strcmp_iw(LIST_ELT, NAME), then the place to start looking is right
3048 where this function would put NAME.
3049
3050 This function must be neutral to the CASE_SENSITIVITY setting as the user
3051 may choose it during later lookup. Therefore this function always sorts
3052 primarily case-insensitively and secondarily case-sensitively.
3053
3054 Here are some examples of why using strcmp to sort is a bad idea:
3055
3056 Whitespace example:
3057
3058 Say your partial symtab contains: "foo<char *>", "goo". Then, if
3059 we try to do a search for "foo<char*>", strcmp will locate this
3060 after "foo<char *>" and before "goo". Then lookup_partial_symbol
3061 will start looking at strings beginning with "goo", and will never
3062 see the correct match of "foo<char *>".
3063
3064 Parenthesis example:
3065
3066 In practice, this is less like to be an issue, but I'll give it a
3067 shot. Let's assume that '$' is a legitimate character to occur in
3068 symbols. (Which may well even be the case on some systems.) Then
3069 say that the partial symbol table contains "foo$" and "foo(int)".
3070 strcmp will put them in this order, since '$' < '('. Now, if the
3071 user searches for "foo", then strcmp will sort "foo" before "foo$".
3072 Then lookup_partial_symbol will notice that strcmp_iw("foo$",
3073 "foo") is false, so it won't proceed to the actual match of
3074 "foo(int)" with "foo". */
