Yep, this code has negated error code returns in it. Irix keeps errno
values positive in the kernel and only at the system call level do they
get flipped, the linux convention of when they get set negative is different.
We are doing a check to look for other occurences of this and a fix with
all the cases we find should be along fairly soon.
