 There are several ways to address this difficulty, regardless of the

+One way is to use --enable-runtime-pseudo-reloc switch. This leaves the task

+A second solution is to force one of the 'constants' to be a variable -- 
 that is, unknown and un-optimizable at compile time.  For arrays, 
 there are two possibilities: a) make the indexee (the array's address) 
 a variable, or b) make the 'constant' index a variable.  Thus:
