Bug Fixes

BZ#802559
Previously, in the xorg-x11-proto-devel package, the definition of the _X_NONNULL macro was incompatible with C89 compilers. Consequently, C89 applications could not be built in C89 mode if the X11/Xfuncproto.h file was included. This update fixes the macro definition to be compatible with C89 mode.
BZ#804907
Prior to this update, XI2 events were not properly initialized and could contain garbage values. A patch for the libXi package, which had been setting values to garbage, has been provided to fix this bug. Now, actual events no longer contain garbage values and are initialized as expected.
BZ#871460
Previously, the spec file of the xkeyboard-config package used the %{dist} macro in the Version tag. Although the standard Red Hat Enterprise Linux build environment defines this macro, it does not need to be defined. If it was not defined, %{dist} appeared literally in the resulting RPM package's version string when the package was rebuilt. The spec file has been corrected to use the conditional %{?dist} form, which expands to an empty string if %{dist} is not defined.
Users of Core X11 libraries are advised to upgrade to these updated packages, which fix these bugs and add various enhancements.
