Colin.

I checked out 2 copies of bootldr as suggested.

Under arm-linux-gcc 2.95 bootldr.small is 54912 bytes, under 3.3.4 it is 
  51072 - a difference of 0xf00.

Please find the files attached for testing.

I suggest installing the 2.95 and using it to install another 2.95 to 
demonstrate that its all happy.

If you want a 2.95 fast I can send that later on.
