Description Chris Coleman 2010-10-30 07:58:59 UTC

The configure script in the three most recent releases of xorg-server define CWARNFLAGS without -fno-strict-aliasing.

xorg-server-1.9.0.901.tar.bz2   
xorg-server-1.9.0.902.tar.bz2   
xorg-server-1.9.1.tar.bz2

In git, all versions of util/macros since version 1.2.0 define CWARNFLAGS with -fno-strict-aliasing. But these three releases have replaced that flag with -Wstrict-aliasing=2.

These releases were apparently created with a patched version of util/macros. Possibly the patch that is attached to the following bug report in comment #7:

The omission of -fno-strict-aliasing has caused a bug in Gentoo Linux involving xkb:

Comment 1 Chris Coleman 2010-11-03 15:37:14 UTC

This has been fixed with xorg-server-1.9.2.tar.bz2.

Many thanks.
