This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.
gdb/ChangeLog:
Update copyright year range in all GDB files.
This is just a testcase addition that I am proposing for upstream GDB.
We have this in our internal tree, and the related RH bug is:

This bug is about a global variable that got incorrectly displayed by
GDB. This bug has already been fixed a long time ago by Joel's
commit:

But I think a testcase for it wouldn't hurt.
So, consider the following scenario:
$ cat solib1.c
int test;
void c_main (void)
{
test = 42;
}
$ cat solib2.c
int test;
void b_main (void)
{
test = 42;
}
$ cat main.c
int main (int argc, char *argv[])
{
c_main ();
b_main ();
return 0;
}
$ gcc -g -fPIC -shared -o libSO1.so -c solib1.c
$ gcc -g -fPIC -shared -o libSO2.so -c solib2.c
$ gcc -g -o main -L$PWD -lSO1 -lSO2 main.c
$ LD_LIBRARY_PATH=. gdb -q -batch -ex 'b c_main' -ex r -ex n -ex 'p test' ./main
...
$1 = 0
This happened with GDB before Joel's commit above. Now, things work
and GDB is able to correctly display the nested global variable:
$ LD_LIBRARY_PATH=. gdb -q -batch -ex 'b c_main' -ex r -ex n -ex 'p test' ./main
...
$1 = 42
The testcase attached tests this behavior.
