In fact, __sputc is defined as
static inline
without the leading underscores (at least in both 386bsd 0.1 and NetBSD).
When the -ansi switch is given, gcc seems to ignore both the static and
the inline rather than giving an error, hence making the function global.
Just add two underscores to the inline in /usr/include/stdio.h as in
static __inline int __sputc(int _c, FILE _p) {
and the problem will go away (presumably this lack of underscores is just
a typing mistake).
