State-Changed-Why:
    not a bug. You need an out of class definition of those
    static members. (It is an opportunity for optimization,
    though)

 Thanks for your prompt reply.  The reason that I believed it to be a bug is that if
 you subtly change the code the linker error disappears.  Sorry to have wasted your
 time!

>Organization:
>Environment:
Debian sid on 80x86, Linux 2.4.19-pre8
>Description:
Comiling the supplied tiny test program (g++-3.0 test.cc) results in the following linker errors (binutils version 2.12.90.0.14-1):
/tmp/ccKTBRxn.o: In function `main':
/tmp/ccKTBRxn.o(.text+0x17): undefined reference to `Fred::BIT1'
/tmp/ccKTBRxn.o(.text+0x21): undefined reference to `Fred::BIT2'
collect2: ld returned 1 exit status
>How-To-Repeat:
Compile the test program with *no* command line flags and version 3.0.4 (Debian 3.0.4-12 or 3.1.1-0pre3) and observe the linker error messages.
>Fix:
Unknown.  Sorry I'm an application programmer and don't know anything about the compiler internals.  I'd love to learn about it though :-)
