The accompanying file is a precompiled version 4.12 of gdb, but it
also contains the support for using the hardware debugging registers on the
i386/i486.  The commands are 'abreak' and 'wbreak' for access breakpoint and
write breakpoint.  Support for these features is not in the distribution
version of gdb, but being able to use the hardware debugging registers is an
extremely powerful debugging tool.  The patches which were made to the stock
version of 4.12 are in the pub/linux/packages/GCC/src directory.
