4.6.12 #pragma import(__use_full_stdio)
This pragma selects an extended version of microlib that uses full standard ANSI C
input and output functionality.
The following exceptions apply:
• feof() and ferror() always return 0
• setvbuf() and setbuf() are guaranteed to fail.
feof() and ferror() always return 0 because the error and end-of-file indicators are not
supported.
setvbuf() and setbuf() are guaranteed to fail because all streams are unbuffered.
