Hi guys, I believe I found a bug. In this example:

int func_weak() __attribute__((weak));

int func_weak()
{
  return 0;
}


"func_weak" is listed as weak in the final executable. Shouldn't it be turned into a 
strong definition for output? It will also make it unneccessary to change GBD to treat 
C_WEAKEXT symbols like C_EXT.

	* cofflink.c (_bfd_coff_write_global_sym): Turn a weak symbol into
	  a strong one for the final output.
