Subject[2.6 patch] Use -ffreestanding? (fwd)
Hi Andrew,

for the kernel, it would be logical to use -ffreestanding. The kernel is
not a hosted environment with a standard C library.

Linus agreed that it would make sense.

The gcc option -ffreestanding is supported by both gcc 2.95 and 3.4,
which covers the whole range of currently supported compilers.

Could you add the patch below to the next -mm to see whether there are
any problems I didn't find?

TIA
Adrian
