Re: [Ltib] a's in integer output

[Tobias Simon]

Hello Stuart,

Here comes my CONFIG_TOOLCHAIN:
"mtwk-lnx-cfv4e-gcc-3.4.0-glibc-2.3.2-v4e-0.28-8.i686.rpm"

and my CONFIG_TOOLCHAIN_CFLAGS:
"-mcfv4e"

These settings were stolen from an earlier version of the "mcf547x_8x" 
platform. I will now try it with the 4.1 toolchain.

Regards,
Tobi
