Subject:	<errno.h> and C99: EILSEQ [PATCH]
Message-Id:	<E18fLVs-0000iE-00@phekda.freeserve.co.uk>

Hello.

Below is a patch that adds the EILSEQ error code, which is required by C99.

Can anyone confirm that EILSEQ definitely wasn't in C89? I am assuming
that it wasn't, because it wasn't in the header before.

OK to commit?

Thanks, bye, Rich =]
