>First I should point out that we do not have any configuration of ELDK 5.0
yet that supports the PPC4xx or PPC44x processors.  Yous, you can use the
powerpc configuration, but this is unsupported and you are on your own if
you run into any problems.

POH:Do you have any timeframes of when  PPC4xx or PPC44x processors will be
supported in ELDK 5.0?

>The option "-enable-target-optspace" should be enabled in the configuration
when building gcc, but thjis is impossible at the moment due to a number of
regressions in recent versions of GCC.  See for example

4.6.x).

POH: Thanks for the pointers to these, noted.
