[jira] Commented: (TS-135) support for atomic operations for 64bit oses without gcc atomic support

["John Plevyak (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TS-135?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12864094#action_12864094 ] 

John Plevyak commented on TS-135:
---------------------------------

Turns out the atomic_ops files we would need in the boehm GC code 
are under an MIT style license.

In terms of correctness and portability, short of vender libraries
this is probably the best portable library out there.
