Which version of GCC ignores usingd-declaration at function scope?

It is well known that GCC-2.95.x's implementation of the standard
library is a masquarad as it doesn't really put its library in std::.
However for that series, saying `using std::abs' effectivelly brings
the corresponding function (::abs) into scope.

`int' are designed to be C++'s primary choices for integer types.
'char' and variants are best thought of as character types and should
not serve for airthmetics -- even if in Standardese they are called
arithmetic types. And they don't play very well with arithmetics.
