from stdio.h:

extern int getchar(void);
#define getchar() getc(stdin)

extern int putchar(int);
#define putchar() putc(c, stdout)

I think the problem basically is that I do not fully understand what is 
done in all those other OSes defined in fpurge.c and what is expected 
from this function.... Sorry for being so nooby. I am basically (for 
fun) trying to port stuff to Plan9 as a hobby project [1] and ran into 
this issue when trying to port GNU m4 and I am sort of lost...
