Could it be that the IOWR_ALTERA_AVALON_PIO_SET_BITS() and
IOWR_ALTERA_AVALON_PIO_CLEAR_BITS() macro do not work because i derived my project from the "Hello World Small" template?

I don't think so. I can't see any relation with the template. No OS or drivers are involved. This is only a matter of writing a register.
Further suggestions:
- try to write the actual set/clear registers (base+4, base+5) instead of using the macros
- make sure you are loading the correct fpga configuration which includes the sopc where you enabled the bit set feature.
- try with another pio port, 8bit wide (if you don't have free fpga pins for the new pio, add one more pio for reading the status with a loopback )
