I have the same problem (multiple definition) with STM32CubeFX 4.25, but no warnings about wchar_t usage.
'multiple definition' errors are caused by duplicates in generated Makefile. After duplicates removal the project is compiled without errors using arm-none-eabi-gcc 4.8.3-2014q1.
May be the wchar_t warnings are compiler version specific (or compiler settings - flags).
I have the same issue with arm-none-eabi-gcc 4.9.3, and I also get warnings about wchar_t.
Just like Jan, I found that the generated Makefile had duplicate entries for 'src/main.c' and 'src/stm32f0xx_it.c', and removing those fixed the project to the point where it would compile, although it did not remove the warnings.
