Subject: [Bug c++/20164] New: Wrong line number in diagnostic with gcc 4.0

When I compile the source file given below with gcc40 I get strange warnings.
I use the snapshot 20050220, but with older snapshots i get the same results.
The function is correct but the line number is wrong.
By the way: Why is "." replaced by "$" ?

g++40 -v
Using built-in specs.

Configured with: ../gcc40/configure --prefix=/usr/local/gcc40e --program-
