AW: Building RPMs for i386

[Carsten Boehlke]

It is the same wether I use "--define 'RPM_OPT_FLAGS=-O2 -g -m32' --target
i386" or "CC="gcc -m32" rpmbuild ..." 
In both cases I get errors:

C compiler cannot create executables
or
cc1: CPU you selected does not support x86-64 instruction set

Does I use a wrong compiler? What was my mistake???

Carsten.
