Hi :
   I am using the gcc compiler. If I use -fpack-struct option to
compile my c program, it packs the structure on a byte boundary.

How can I force gcc to pack on word boundary?

Is there another option or command for packing on word boundary?

Thanks

use the aligned (NR_BYTES) (or __aligned__ (NR_BYTES) for header files) to 
pass gcc the alignment for an object - see the section "Specfiying Attributes of Types" in the gcc info pages.
