ABI changes on specific architectures only

[Norbert Tretkowski <norbert@tretkowski.de>]

Hi,

I switched the alpha build from gcc-3.3 to gcc-4.0 in the not yet
uploaded 2.6.14-3, and Jurij said he'll also switch sparc from gcc-3.3
to gcc-4.0.

How to handle these ABI changes for specific architectures?

Thanks, Norbert
