newlib/time.h overload "cannot overload functions distinguished by return type alone"

[AxBaEn]

When trying to "#include time.h" in a platformIO project the compiler raises error:

In file included from src/main.cpp:14:0:
/home/axel/.platformio/packages/framework-wizio-pico/wizio/newlib/time.h:47:18: error: conflicting declaration of C function 'unsigned int micros()'
unsigned int micros(void);
^~~~~~
compilation terminated due to -Wfatal-errors.

and in the file newlib/time.h the offending function micros() is marked with error "cannot overload functions distinguished by return type alone".

The platform is linked in the platformio.ini file with "platform = https://github.com/Wiz-IO/wizio-pico.git"
