PATCH 21.5 Fix VDB detection on x86_64 Macs. SJT> I just tried, and it tried to use PPC code. I configure --with-newgc frequently on my Intel Mac, but never saw the problem you hit since my configure arguments also set the VDB explicitly. Thus, I missed that configure fails to determine the right virtual-dirty-bit write barrier on 64-bit Macs. This patch fixes it, I'll commit in a few days, if nobody objects. # HG changeset patch # User Marcus Crestani <crestani(a)informatik.uni-tuebingen.de&gt; # Date 1378669689 -7200 # Node ID a9fd35f939a5ab86f3907d5492f70d8ab6a884d2 # Parent 995257d0c590d72c2ae483054d5361bff947d19d Fix VDB detection on x86_64 Macs. diff --git a/ChangeLog b/ChangeLog --- a/ChangeLog +++ b/ChangeLog ＠＠ -1,3 +1,9 ＠＠ +2013-09-08 Marcus Crestani <crestani(a)xemacs.org&gt; + + * configure.ac: x86_64 Macs also use POSIX virtual-dirty-bit write + barrier. + * configure: Rebuild. + 2013-07-28 Stephen J.
