Need some unions or a sprinkling of -fno-strict-aliasing ? This is using the recent webkitgtk-2.3.91 tarball. 987657 1 225981 prlw1 2014-03-06 05:27:36 -0800 Created attachment 225981 Sticking plaster to fix build This patch gets webkitgtk-2.3.91 building a bit further. Given that the type punning seems intentional, maybe a more legal way of doing it involving unions should be sought. Suggest applying said patch, and leaving bug open. 225981 2014-03-06 05:27:36 -0800 2014-03-06 05:27:36 -0800 Sticking plaster to fix build patch-GNUmakefile.in text/plain 614 prlw1 JE5ldEJTRCQKClN0aWNraW5nIHBsYXN0ZXIgZm9yIGludGVudGlvbmFsIHR5cGUgcHVubmluZy4K aHR0cHM6Ly9idWdzLndlYmtpdC5vcmcvc2hvd19idWcuY2dpP2lkPTEyOTY4MwoKLS0tIEdOVW1h a2VmaWxlLmluLm9yaWcJMjAxNC0wMy0wNCAyMzozNjoyOS4wMDAwMDAwMDAgKzAwMDAKKysrIEdO VW1ha2VmaWxlLmluCkBAIC0xMzc3MCw3ICsxMzc3MCw3IEBAIGphdmFzY3JpcHRjb3JlX2NwcGZs YWdzIDo9IC1JJChzcmNkaXIpL1MKIAktSSQodG9wX2J1aWxkZGlyKS9EZXJpdmVkU291cmNlcy9K YXZhU2NyaXB0Q29yZSBcCiAJLUkkKHNyY2RpcikvU291cmNlL1dURiAkKExMVk1fQ0ZMQUdTKQog amF2YXNjcmlwdGNvcmVfY2ZsYWdzIDo9ICQoZ2xvYmFsX2NmbGFncykgJChHTElCX0NGTEFHUykg XAotCSQoTExWTV9DRkxBR1MpICQoVU5JQ09ERV9DRkxBR1MpCisJJChMTFZNX0NGTEFHUykgJChV TklDT0RFX0NGTEFHUykgLWZuby1zdHJpY3QtYWxpYXNpbmcKIGphdmFzY3JpcHRjb3JlX3NvdXJj ZXMgOj0gIFwKIAlTb3VyY2UvSmF2YVNjcmlwdENvcmUvQVBJL0FQSUNhbGxiYWNrRnVuY3Rpb24u aCBcCiAJU291cmNlL0phdmFTY3JpcHRDb3JlL0FQSS9BUElDYXN0LmggXAo=
