No problem! I can wait...

I haven't tried it yet but it did compile.

So far I have not yet seen an error. Maybe all these warnings come because I am using
llvm-gcc on Darwin and llvm is much more critical in its default warning level.

Most warnings are about const qualifiers, missing initializers and comparisons
of signed and unsigned values.

The result looks like this:

iMac:replicant-4.0 hns$ ls -l out/target/product/gta04/system.tar.bz2 out/target/product/gta04/kernel
-rw-r--r--  1 hns  hns    3710860  4 Jul 11:01 out/target/product/gta04/kernel
-rw-r--r--  1 hns  hns  139059457  4 Jul 15:21 out/target/product/gta04/system.tar.bz2
iMac:replicant-4.0 hns$ 

But I have not tried to run it.

This is why I am writing down every step - others from the Replicant
project may find that eventually helpful (even for non-GTA04 devices).

On Darwin it appears to (cross) compile on 32 bit mode as well.

BR and tnx again for what you already have achieved!
