#261 iosfwd bloat

[Lars Christensen]

A simple #include <iosfwd> results in 14k lines being included,
including windows.h, winbase.h etc resulting in increased
compile times.

On a posix system including cygwin, this
only includes less than 1.2k lines.

Shouldn't really be
necessary to include that much.
