Sure I can, this was approach b I suggested. But that may be harmful to
performance, as it forbids gcc to use any knowledge about the standard
library (includes inlining of memcpy with small constant sizes or
built-in pureness annotations).

But the issue that started the discussion was: What to do about the
scanf warning? On a system that does not have wchar builtins in gcc,
currently all built-in functions are enabled. Even on these systems, we
should disable the built-in scanf to prevent the warning in the scanf
test. This need has long been unnoticed, as wchar ctype functions are
built-in on our main development platform.
