RHBA-2007:0101 - Bug Fix Advisory

Topic

Updated GNU Compiler Collection (GCC) packages that use system timezone
data in libgcj4 instead of providing libgcj4's own

Description

The gcc4 packages contain technology previews of the GNU Compiler
Collection version 4.x. They include C, C++, Fortran 95 compilers
and a Java compiler and support libraries.

These packages provide updated timezone information for libgcj4, GCC 4.x
technology preview runtime library.

libgcj4 previously used its hardcoded simple timezone information. This
information was not kept up to date with the system timezone data
updates and did not handle historical daylight saving information.
Instead, it used the latest applicable daylight saving time changing
rule for each timezone as of the time the gcc release branch had been
created.

These updated packages read the timezone information data from system
tzdata package files and are able to handle daylight saving time
transitions even for past years.

For full details regarding all fixed bugs, refer to the package changelog
as well as the specified list of bug reports from bugzilla.

All users of gcc4 should upgrade to these updated packages, which resolve
this issue.
