Hi,

Generally in the case of failure, the system calls will store the errnum in
%eax and call cerror which will in turn store the error number in _errno. This
code existed before and somewhere in the middle was deleted during one of the
changes. The net result is that the error number returned by the kernel will be
lost.

Maybe it needs to be reinstated.

Following are the suggested changes:

diff -u cerror.S*
--- cerror.S    Tue Nov 25 11:17:15 2003
+++ cerror.S.orig       Tue Nov 25 10:38:42 2003

        movl    $-1,%edx
        ret


Thanks,
Srini.
