Building the following simple test case 

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

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

gcc -g hello.c -o hello

$ gcc -v

gcc version 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)
----------------------------------------

with GCC-3.4.4-2 (EXP) seems that the debug symbols are not added to 
the executable.


GDB says:

--------------------------------------------

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




But building the testcase with GCC-3.4.4-1 causes a different beaviour (I
think correct):


With GCC-3.4.4-1:
-------------------------------------------------------------
gcc -g hello.c -o hello

$ gcc -v
