--- Comment #10 from gcc <shalja.rudra at gmail dot com> 2012-05-04 20:11:50 UTC --- I looked into the similar post in boost mailing list http://lists.boost.org/Archives/boost/2011/07/184266.php and it directed to http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49445 The email got bounced before using the gcc-h...@gcc.gnu.org, may be the email was not plain text format . It is fine now. Thanks (In reply to comment #9) > Bugzilla is not a help forum. Please find somewhere more appropriate to ask > how to solve your problems, such as the boost mailing list or the gcc-help > list.
