The stabs debugging format only supports upto 65535 lines (hmm 16bit 
unsigned ...).  Unless you're going to try debugging that file it isn't 
that important (it can be solved by specifying dwarf 2 debug format - 
see GCC and the -g option).

These a Altivec instructions and not part of a core PPC, hence the're 
dropped.  Again not an immediate concern.
