Hi, I tried to use printf in a cross 68k machine. The print "unsigned long long" seems not to work.

unsigned long long a = 9888994872930475ull;
printf("%llu", a)
-> gives as a result 2302461                       on my cross target 68k
-> gives as a result 9888994872930475  on my host machine OSX
How do I have to configure newlib to correctly support long long int on embedded targets?

Specify --enable-newlib-io-long-long when you configure newlib prior to building it.
