Update of /cvsroot/mspgcc/gcc/gcc-3.3/gcc/config/msp430
In directory sc8-pr-cvs16.sourceforge.net:/tmp/cvs-serv23290/gcc/config/msp430

Modified Files:
	libgcc.S msp430.h 
Log Message:
- remove the hack
- ensure that _do_clear_bss is linked when .comm symbols are output (these are linked into the .bss secion too and unless -fno-common is given it is the default type for unitialized globals)
