There is an open Magenta issue to rename these with a MX_ prefix.

See: MG-697

MG-835 upstream. I guess we'll probably have to do the #undef dance and hope net doesn't actually need to check for TIMED_OUT from a syscall.

Oops, crossed comments. Thanks swetland!

Looks like this happened upstream: https://fuchsia-review.googlesource.com/#/c/33721/

So we just need an SDK roll I guess?

That CL adds the MX_ prefixes, but I don't think the conflicting ones are removed yet. We could probably get away with a few #undefs after that CL though (maybe that's what you meant...)

I wanted to get a `cat` binary added too (all the newest fanciest tech!) https://fuchsia-review.googlesource.com/c/34189/ and then it'd be good to update to latest Fuchsia to get some of the fixes that have landed recently.

Oh durr. kulakowski, can we add the old symbols behind some `#ifndef MX_OLD_MACRO_NAMES` thingy or similar?

Yes, there's a #ifndef USE_MX_ERRORS already in there.

The following revision refers to this bug:

Update Fuchsia SDK to f79f55be4e69ebd90ea84f79d7322525853256c3

Two notable changes:
- realpath() works.
- ERR_TIMED_OUT, et al. are guarded and MX_ prefixed are available.


Steps followed (mostly in Fuchsia tree):
- check if fuchsia-dashboard.appspot.com looks green
- sync
- fbuild
- fboot on Intel NUC
- runtests on device and make sure everything passes
- configure and build a release mode build with sdk config:

$ ./packages/gn/gen.py -r --goma -m runtime
$ ./packages/gn/build.py -r -j1000

- assemble sysroot and package tools into tgz

$ ./scripts/makesdk.go .

- compute sha1

$ sha1sum fuchsia-sdk.tgz
f79f55be4e69ebd90ea84f79d7322525853256c3

- upload to gs bucket

$ gsutil.py cp fuchsia-sdk.tgz gs://fuchsia-build/fuchsia/sdk/linux64/f79f55be4e69ebd90ea84f79d7322525853256c


Then, on the chromium side, update DEPS to point at this sdk rev, build
and confirm things are OK-ish, and make any changes required.
