OK.  I am not that sure about how gdb handle that.  Daniel ever told me 
that we can fix this in gdb's side by setting the main function to 
"MAIN__" for Fortran programs.

It seems to me that emitting DW_AT_entry_point in gcc's side is a better 
idea.  But I am not sure whether gdb could handle it.  When gcc do emit 
DW_AT_entry_point, I will verify that.  I had added myself into the 
cc-list.
