You could try, but I can't think of any changes that would be
considered suitable for upstreaming. To list notable differences off
the top of my head:

- void* is replaced with va_list where appropriate.
- some version code to whom's identifiers are only emitted from the
gdc compiler.
- some functions in std.math call the long double rather than double
math lib functions.
- std.format.doFormat has some difference for consideration that the
va_list varies on differing architectures.
