We're seeing this problem on s390 as well.  (B.t.w. this doesn't 
appear to have anything to do with "builtin functions", does it?) 
 
>From my initial experiments, it would appear that the problem 
is caused by the K&R-style function definition -- when using 
a C89-style definition like 
int fputs_unlocked (const char *str, int *fp) 
everything works as expected. 
 
Maybe something goes wrong when merging attributes between the 
declaration and definition type nodes in case the latter is K&R?
