/* Linux uses a negative return value to indicate syscall errors,

Since version 2.1 the return value of a system call might be
|
|
negative even if the call succeeded. E.g., the `lseek' system call
|
|
might return a large offset. Therefore we must not anymore test
|
|
for < 0, but test for a real error by making sure the value in %eax
|
|
is a real error number. Linus said he will make sure the no syscall
|
|
returns a value in -1 .. -4095 as a valid result so we can savely
|

test with -4095. */
