RE:[PATCH,AIX] Enable FFI Go Closure on AIX

["REIX, Tony" <tony dot reix at atos dot net>]

Hi,

We have built and installed the libffi master of yesterday on a AIX 6.1 machine and we have rebuilt and tested Python3 (3.5.2) with this libffi. And that is OK. 32bit and 64bit.

5 more tests were run and succeeded.
And 1 test (test_ssl) which was skipped before is now run but failed due to no access to Web (Resource 'sha256.tbs-internet.com' is not available).

So. our patch does not break libffi build and tests, nor Python3 build and tests.

That looks OK.

We'll submit the patch to the libffi project now.

Regards,

Tony

Libffi project now is on Github

https://github.com/libffi/libffi

I think that Anthony now uses pull requests.

Once the patches are in the upstream project, we can backport them to GCC.

Thanks, David
