+/* This is like strcmp except that it ignores whitespace and treats

+ strcmp (and unlike strcmp_iw), it returns negative if STRING1 <
+ STRING2, 0 if STRING2 = STRING2, and positive if STRING1 > STRING2
+ according to that ordering.
+
+ If a list is sorted according to this function and if you want to
+ find names in the list that match some fixed NAME according to

+ where this function would put NAME.
+
+ Here are some examples of why using strcmp to sort is a bad idea:
+
+ Whitespace example:
+
+ Say your partial symtab contains: "foo<char *>", "goo". Then, if
+ we try to do a search for "foo<char*>", strcmp will locate this
+ after "foo<char *>" and before "goo". Then lookup_partial_symbol
+ will start looking at strings beginning with "goo", and will never
+ see the correct match of "foo<char *>".
+
+ Parenthesis example:
+
+ In practice, this is less like to be an issue, but I'll give it a
