Subject: typo? and static with extern


Hi, Scott, 
    I bought Effective C++ (Version 3) this week. I like it and is reading it. I have two issues:

1. On page 52 paragraph 2, lines 3 and 4, Should 'that' be 'than' in: ... more convenient(and more readable) that going through contortions in the member initialization list to .... ?

2. Page 30 talking about non-local static objects. As I understand, if you declare one object, say, 
                 static FileSystem tfs; 
in file A.C
The linker will complain when  you  have:
    exterm FileSytem tfs;         //as shown on page  30 
in file B.C

I means this extern on page 30 will not be invalid?




=============================================================================================
The following shows the output when I declared static int i; in A.C and extern int i in B.C and when I compiled the two files:

CC A.C -o a.o B.C
A.C:
B.C:
Undefined                       first referenced
 symbol                             in file
i                                   B.o
ld: fatal: Symbol referencing errors. No output written to a.o

shell returned 1
