with this possible switch the compilation running on powermac.g4 without 
problem.

CFLAGS="-arch x86_64 -arch i386" g++ -o pot64bit ./potenzieren.c
but stil don't run on me windows 64bit machine

if trying 
CFLAGS="-arch x86_64 -arch i386" gcc -o pot64bit ./potenzieren.c
here me compiler don't found the included files

powermac$ CFLAGS="-arch x86_64 -arch i386" gcc -o pot64bit ./potenzieren.c

./potenzieren.c:4:42: error: iostream: No such file or directory
./potenzieren.c:7: error: expected '=', ',', ';', 'asm' or '__attribute__' 
before 'namespace'
./potenzieren.c: In function 'main':
./potenzieren.c:24: error: 'cout' undeclared (first use in this function)
./potenzieren.c:24: error: (Each undeclared identifier is reported only once
./potenzieren.c:24: error: for each function it appears in.)
./potenzieren.c:24: error: 'endl' undeclared (first use in this function)

thanks for any feedback
regards
