[bug #63866] error: expected expression

[Ryan Carsten Schmidt]

Follow-up Comment #6, bug#63866 (group gettext):

The gnulib build results I posted on Jan 26 were not from OS X 10.9 so I'm not
sure why I posted them. I think I was using OS X 10.11 which does not have the
affected clang version.

I tried your latest gnulib tarball on OS X 10.9. ./configure and make
succeeded. make test failed one test, test-fma2, but I don't think that's
related to this issue.

gettext 0.22.4 still fails to build on OS X 10.9 with the error I originally
reported. Here is the first error and a warning; there are many more warnings
but as you said we're not as concerned with the warnings:


x-c.c:1561:15: error: expected expression

Here's how I fixed it in MacPorts:
