error: typedef 'funcPtr' locally defined but not used

stm32f4/libmaple/libmaple/usb/usb_hardware.c:87:20: error: typedef 'funcPtr' locally defined but not used [
-Werror=unused-local-typedefs]
typedef void (funcPtr)(void);
^
cc1.exe: all warnings being treated as errors
make: ** [build/./libmaple/usb/usb_hardware.o] Error 1

my temporary fix for the above was to edit the line usb_hardware.c and comment the line 87, i tried the -Wno-unused-function flag with cxx flags but it didn't fix the problem.

I don't understand why is the above typedef void (*funcPtr)(void); defined in systemHardReset(void) method in usb_hardware.c file; isn't it supposed to be in .h file
