Excellent.

BTW, there are quite a few patches being submitted to add
gcc-3.4 support to the mainline kernel.  I wouldn't be surprised
if a patch or two were needed.  For instance, have a look at

http://marc.theaimsgroup.com/?l=linux-kernel&m=109155989525571&w=2

Which kernel were you trying to compile?  Oh, linux-2.4.21 for arm.
Yeah, I bet that doesn't have any gcc-3.4 fixes in it yet.  Can
you try a more recent one?
