indeed fixes this. Well, it suggests:
pr71858.c: In function ‘main’:
pr71858.c:4:10: warning: implicit declaration of function ‘bar’; did you mean
‘char’? [-Wimplicit-function-declaration]
return bar ();
^~~
char
instead. Which actually also isn't a very good suggestion for C (unlike C++),
it would be useful to consider only FUNCTION_DECLs in this case.
