I think this code is too complex. Eventually we could hard-wire something like ". = 0x40000" or similar for a fixed location of the (pre-relocation) bss on all 85xx/86xx systems. > > 2. is 1 in C and some common supporting asm for ppc.

Um... jut to be sure - I understand that by "all architectures" above you actually mean "all Power architecture CPU families", i. e. you don't include the needed cleanup for ARM, MIPs, etc. here (yet) ?
