[Bug manual/3665] New: errno 118 assigned twice (ECANCELED and ENOTSUP)

[Bug manual/3665] New: errno 118 assigned twice (ECANCELED and ENOTSUP)

[samuel dot thibault at ens-lyon dot org]

In manual/errno.texi, 118 is assigned twice: both to ENOTSUP and to
ECANCELED.

That makes 

switch(errno) {
	case ENOTSUP:
		foo();
		break;
	case ECANCELED:
		bar();
		break;
}

not compilable on systems that make use of these numbers for defining
E* constants (the Hurd, for instance).

proposed patch

Here is a proposed patch.

ECANCELED is only supported for aio functions, which have yet no implementation
on the Hurd: the symbols aren't even provided, so no existing program may have
already been compiled using that 118 value.  That's why it is safe to change
that constant rather than ENOTSUP.

So, what do you think of this?  This is currently blocking building kdelibs on Debian, I'd like to know how this should be fixed before submitting a patch to debian's glibc package.

This patch has been applied; now `mach/hurd/bits/errno.h' has to be regenerated.
 A patch has been posted in
<http://sourceware.org/ml/libc-alpha/2007-07/msg00089.html>.
