	That depends on the situation, of course.  For allocating arrays that
are auto-initialized, how else is the program to know what values the
array should have at startup?  Have the program code fill the array at
run-time?  That takes much more disk space to write the code overhead. 
The only optimization in this case (that I can think of) is to have gcc
check if the array is hard coded to autoinitialize to all zeros.  If so,
then the startup code could be generated to run a small loop to write
zeros to all locations.  That case would eliminate disk bloat for large
global arrays.
