Well, that's disappointing :)

This still looks like a GCC issue. The C standard in
Yes, it seems that gcc and clang disagree on how to interpret const. Here's a

Hey David,
It might be that libobjc2 no longer supports gcc, but in case it does, this
is the result of building with Ubuntu 16.04's gcc 5.4.0:

It might be fixed in a later GCC version (I'll see if I can deploy one),

I'm fiddling with writing Bazel (http://www.bazel.io/) BUILD-files for
libobjc2 (and, hopefully, other GS libraries). There are reasons why I'm
doing this, but they're a separate discussion topic.

Hello GNUstep people,
There are lots of recent changes in libobjc2, including AArch64 support and
significant reworking of both the message send and block-as-imp code paths
(i.e. all of the assembly code).
I’d like to do a new release soon, but it needs a lot wider testing. Please
try
untu that don't ship with a sufficiently new clang.)
