For some reasons with ppc I have to add -std=c99 to my CFLAGS if I compile with gcc-4.4.3 - note that it is not necessary with gcc-4.3.4 on ppc or gcc-4.4.3 on x86. Just adding that got me to a further failure to lisp bootstrapping (that I had with gcc-4.3.4).
Removing all other flags however seems to have done the trick, so there may be one that is dodgy to ecls in the lot. I will see if building has finished later, cross finger :) If it does I may take some time to see which flag(s) lead to the failure. In the meantime I also asked for help from the ppc forum.
