Arm Compiler Arm C and C++ Libraries and Floating-Point Support User Guide : Using macro__ARM_WCHAR_NO_IO to disable FILE declaration and wide I/O function prototypes

Using macro__ARM_WCHAR_NO_IO to disable FILE declaration and wide I/O function prototypes

You can define the macro __ARM_WCHAR_NO_IO to cause the wchar.h and cwchar header files not to declare FILE or the wide I/O function prototypes.

Declaring the FILE type can lead to better consistency in debug information.
