You can not rule out other software embedding python inside, or callbacks from foreign code.

For instance, Solaris system libraries are not compiled using GCC.

Would be nice if GCC 4.5.1 would solve this :). They are objectivelly breaking the x86 ABI. - -- Jesus Cea Avion _/_/ _/_/_/ _/_/_/ j...@jcea.es - http://www.jcea.es/ _/_/ _/_/ _/_/ _/_/ _/_/ jabber / xmpp:j...@jabber.org _/_/ _/_/ _/_/_/_/_/ . _/_/ _/_/ _/_/ _/_/ _/_/ "Things are not so easy" _/_/ _/_/ _/_/ _/_/ _/_/ _/_/ "My name is Dump, Core Dump" _/_/_/ _/_/_/ _/_/ _/_/ "El amor es poner tu felicidad en la felicidad de otro" - Leibniz -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQCVAwUBS+q0rplgi5GaxT1NAQK98wP+NJoqNCpvjemP4Gv7y1G/iPkQgjuidslT uiPxDcN9Eprcluc+mGTBu6N+fCTj09xYhUCD1wWhoJq2dRyoA8b+XC1fCSyL4VXc mzsy0rGmKeQh4lyAw+7agFCqryd6n+/oyl+9aOT6YkzyLFjQd4KDEcGNZ0h+6PAf 4jtx1+p3k0c= =TzTY -----END PGP SIGNATURE----- _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
