Building 

----------------------------------------
$ cat hello.c
#include <stdio.h>

int main()
{
    printf("Hello, World!");
    return 0;
}

gcc -g hello.c -o hello
----------------------------------------

with gcc-3.4.4-2 (EXP) causes GDB ignoring the debug symbols:

--------------------------------------------
$ gdb ./hello.exe

                                              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
(gdb)
--------------------------------------------

But building the testcase with GCC-4.0.3 or GCC-4.3.0 causes a different
beaviour (I think correct):



With GCC-4.0.3:
-------------------------------------------------------------
/usr/local/g95/bin/gcc -g hello.c -o hello-4.0.3.exe

$ /usr/local/g95/bin/gcc --version

(gdb)                                          ^^^^^^^^^
-------------------------------------------------------------


With GCC-4.3.0
-------------------------------------------------------------
/usr/local/gfortran/bin/gcc -g hello.c -o hello-4.3.0.exe

$ /usr/local/gfortran/bin/gcc --version
