Re: [Ltib] a's in integer output

[Stuart Hughes]

Hi Tobi,

Can you send me a copy of your config/platform/<target>/.config, or let
me know what the values of CONFIG_TOOLCHAIN and CONFIG_TOOLCHAIN_CFLAGS

I notice in CVS that for the cobra5475 it is 
mtwk-lnx-cfv4e-gcc-3.4.0-glibc-2.3.2-v4e-0.28-8.i686.rpm, if you're
using that, you could try adding a later toolchain that we have for the
mcf547x_8x with a patch like this:

It you add this toolchain you'll need to run ./ltib --configure and
select the new toolchain.  It will force a full rebuilt.

If this is the fix, then I'll let the Coldfire team know that there is a
problem with that toolchain.

Regards, Stuart
