Exactly. That's why (if you continue reading my previous posting), I say
that when compiling normal code (as opposed to static initialized data)
you get lots of grief.  If those large tables are put into a separate
file (I usually have large static tables in separate files anyway), then
that file only could be compiled with the -R flag.  Other files, of course,
won't be affected.
