MPLAB-C18 requires an explicitly defined segment. Can only
do all-or-nothing -- that's why OSLOC_ALL cannot be used.


ICCAVR users can force Salvo's global objects into a unique
program area called salvoram. When used, specify the start
and end addresses of this program area via:  
          
 	-bsalvoram:0xstart.0xend    
                       
as a linker option. Otherwise the salvoram program area will
simply follow the data program area (default).
