OK, so a few thoughts here.
- What's the portable way to do hex-based math? If we really need it?
Use printf(3) to convert to/from hex, and standard shell arithmetic with $(( )).
Looks horrible, but something like:
v=$(( $( printf "%d\n" 0xa0 ) + $( printf "%d\n" 0x10 ) )) printf "v = %d (%x)\n" $v $v
Can we just assume that awk is available? After all, AWK is defined in the top-level Makefile...
... maybe arranged into some sh helper functions.
