let the .bss section initialize static variables

Browse source 
ISO/IEC 9899:1999 section 6.7.8 specifies the values of static
storage which are not explicitly initialized.  According to that
these initializers can be omitted.  Doing so improvoes future
compatibility against addition / deletion of the fields of this
struct.
