I don't contest the warning, but why is it printed 2 times ?!

Did you read the bug report?  The problem is that the warning is issued 
twice when it should be issued once.

I'd guess that the issue that that the system header declares the function 
with a format attribute, and such an attribute is also built in, and the 
duplicate attributes don't get eliminated properly.

uint32_t is unsigned int on those targets and this is not a bug.
