I've just spent all evening trying to work out why my program
broke, I eventually found that scanf.c contains a static function
called 'index', which is incompatible with index(3).

This normally wouldn't matter, but unfortunately cc/asld don't
implement statics, but instead make them extern (this is at the top
of my wished-fixed list!). This means that any program which uses
both scanf(3), and index(3) will have a broken index, or will fail
at link time with multiple definitions for index.

A temporary fix is to recompile scanf.c, changing index to scnindex,
or some other string that isn't likely to match a user function.

Hope this saves you all the anguish I went through!
