I got the following compile error in 2.6.5-rc2-mm3 using the gcc 2.95
from Debian unstable on i386:

<-- snip -->

...
CC drivers/md/linear.o
drivers/md/linear.c: In function `linear_mergeable_bvec':
drivers/md/linear.c:84: Internal compiler error:

I know that this is on the first hand a compiler bug, but gcc 2.95 is
although no longer supported by the gcc developers still the recommended
compiler for the kernel.
