---------------------------------------------------------------------

1. Topic:

Several bugs have been found and fixed in the GNU Compiler Collection
snapshot which shipped with Red Hat Linux 7.1, and the last errata GCC 
version available for Red Hat Linux 7.0.

2. Relevant releases/architectures:

Red Hat Linux 7.0 - alpha, i386

Red Hat Linux 7.1 - i386

3. Problem description:

This update fixes several Internal Compiler Errors on invalid input as well
as some on valid input. It also fixes a number of cases where code was 
miscompiled.

See the bug IDs and package changelog for more details.

The bug IDs below are those fixed against gcc-2.96-81 which was shipped
in the Red Hat Linux 7.1 / x86 release. You may use the "--changelog" RPM 
option with the GCC RPM to see a list of changes fixed since other 
gcc-2.96-RH releases.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade.  Only those
RPMs which are currently installed will be updated.  Those RPMs which are
not installed but included in the list will not be updated.  Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network.  Many
people find this an easier way to apply updates.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
