Looks good to me; thanks for fixing.


Release managers:

I'd like to apply FX's patch here:
  https://gcc.gnu.org/ml/gcc-patches/2018-02/msg00881/patch
to trunk, to fix the build of jit on OS X, and to make it easier to fix
it on Solaris.

This involves touching gcc/configure.ac (and configure).

I've successfully bootstrapped and regression-tested it on x86_64-pc-
linux-gnu.  FX reports above that it fixes the build on macOS, and
Rainer has an (untested) patch on top of it that ought to fix the build
on Solaris:
  https://gcc.gnu.org/ml/gcc-patches/2018-02/msg00835.html

We're in stage 4, and the two bugs in question:
  PR jit/64089 ("libgccjit.so.0.0.1 linkage failure on darwin")
    https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64089

  PR jit/84288 ("Support jit on Solaris")
    https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84288
aren't regressions.

However, I believe this is a low-risk patch, and is mostly confined to
jit (and those targets).

Is it OK for trunk now, or does this need to wait until next stage 1?

Thanks
Dave
