Patch should apply with 'patch -p1' (i.e., filenames begin with linux/
or a/, b/ etc.)

Thanks for the feedback, here is an updated patch.

By the way: Does anybody know _why_ COMMAND_LINE_SIZE depends
on the architecture? Wouldn't it make sense to generalize it 
for all platforms to e.g. 2048 characters? 

Bye, Jens
